Located in the northeastern part of Tokyo's 23 wards, right on the border of Adachi and Katsushika wards, sit "Ayase" and "Kameari." Separated by just a single station and a distance of approximately 2.2 kilometers, these two neighborhoods are immensely popular areas that almost always come up when searching for a rental property along the Chiyoda or JR Joban lines. Many people find themselves wondering, "I want a comfortable commute where I can get a seat to central Tokyo, but how different is the daily lifestyle between Ayase and Kameari?" or "What are the actual differences in rent prices, shopping convenience, and local safety?"
As explained in our Chiyoda Line Area Guide, which outlines the livability and station-by-station characteristics along the line, the Chiyoda Line is one of Tokyo's premier trunk lines, providing direct access to Kita-Senju, Nishi-Nippori, Otemachi, Kasumigaseki, Omotesando, and Yoyogi-Uehara. Within this network, Ayase Station—a major terminal managed by Tokyo Metro—and Kameari Station—managed by JR East and deeply rooted in a charming shitamachi (traditional downtown) culture—exhibit a clear contrast in daily living convenience and neighborhood character. Drawing on over a decade of hands-on experience in Tokyo's rental market, let's take an in-depth look at these areas, combining local realities with official data from the Ministry of Land, Infrastructure, Transport and Tourism.
- [Conclusion]: "Ayase" is best if you want a seated commute toward Otemachi and Kasumigaseki or prioritize late-night trains. "Kameari" is ideal if you want to enjoy a large shopping mall (Ario), vibrant shopping streets, and weekend strolls.
- [Rent / Expenses]: For single-person apartments (1K/1R), Kameari is about 5,000 to 7,000 yen cheaper. For family-sized layouts (2LDK and above), a reversal occurs where Kameari commands higher rates due to the brand value surrounding the Ario shopping center.
- [Avoiding Mistakes]: Both stations carry flood risks due to being located in the Arakawa and Nakagawa lowlands, so choosing properties on the second floor or higher with modern earthquake-resistant construction is recommended. It is essential to check nighttime street lighting routes around the west and east exits after sunset.
What is the Difference Between Ayase and Kameari? Basic Specs and the Reality of Rent Prices on the Border of Adachi and Katsushika Wards
Although they are neighboring stations separated by just a single set of tracks, Ayase Station is located in Ayase, Adachi Ward, Tokyo, while Kameari Station is located in Kameari, Katsushika Ward, Tokyo. These locations heavily reflect the administrative services and urban planning policies of their respective local governments. Let's start with an overview of land prices, rent levels, and the structural layout of both areas.
Real Estate Value Based on Official Land Prices by the Ministry of Land, Infrastructure, Transport and Tourism and Actual Transaction Examples
According to official land price data (as of January 1, 2024) from the Ministry of Land, Infrastructure, Transport and Tourism's "Real Estate Information Library," the average residential land price in the Ayase area of Adachi Ward is 649,000 yen/m² (approx. 2.145 million yen per tsubo, a 6.9% increase from the previous year), and the average commercial land price is 793,250 yen/m² (approx. 2.622 million yen per tsubo), showing a steady upward trend. In particular, the representative benchmark point at "1-111-2 Ayase, Adachi Ward and others (approx. 80m from the station)" has reached a unit price of 926,000 yen/m², strongly driven by its convenience as a transportation hub.
Looking at recent real estate transaction examples (Q1 2024), residential land (plots) in the Ayase area averaged around 54 million yen (approx. 1.4 million yen per tsubo), while land-and-building packages ranged from 59 million yen to the 64 million yen range. From an urban planning perspective, the area immediately surrounding the station is designated as commercial and neighborhood commercial districts with an 80% building-to-land ratio and a 300% floor area ratio, flanked orderly by medium-to-high-rise exclusive residential districts further out. This stable asset value is strongly reflected in the leasing market's rental conditions.
Comparison of Rent Prices for Single-Person Properties: Why is Kameari About 5,000 Yen Cheaper?
Comparing single-person 1R, 1K, and 1DK layouts, the average rent around Ayase Station is approximately 72,000 to 78,000 yen, whereas around Kameari Station it ranges from 67,000 to 73,000 yen, showing a price difference of roughly 5,000 yen per month. The primary reason for this difference is none other than their railway affiliations (Tokyo Metro versus JR East).
Ayase Station functions as the effective starting and terminal station for the Tokyo Metro Chiyoda Line, allowing passengers to access various parts of central Tokyo at base subway fares. On the other hand, Kameari Station falls under the JR Joban Local Line (all-stations service), which can result in double fares when transferring to other lines at stations like Nishi- Nippori. This overwhelming premium of being a direct-to-city-center metro terminus creates the approximately 5,000 yen surcharge on single-person rents in Ayase.
Rent Reversal Phenomenon for Family Properties and Floor Area Guidelines
However, when shifting focus to family properties with a usable area of around 55m² to 75m²—such as 2LDK and 3LDK layouts—an interesting reversal phenomenon occurs in rent prices. While a 2LDK around Ayase Station ranges from 150,000 to 175,000 yen, newly built family condominiums near Kameari Station's south exit and along the Loop 7 highway are often priced higher, ranging from 160,000 to 185,000 yen.
Behind this trend are the presence of the large commercial facility "Ario Kameari" (detailed later), rich waterside parks including the Nakagawa River, and high praise for Katsushika Ward's childcare support policies. Many family households take the step of "living in Ayase during their single years for transport convenience, then moving to Kameari for its well-established living environment upon marriage and childbirth," leading to a clear division in layout demands.
| Comparison Item | Ayase Station (Adachi Ward) | Kameari Station (Katsushika Ward) | Professional Perspective & Verdict |
|---|---|---|---|
| Single Rent (1K/25㎡) | Approx. 75,000 yen | Approx. 70,000 yen | Kameari is about 5,000 yen cheaper. Advantageous for cutting fixed costs. |
| Family Rent (2LDK/60㎡) | Approx. 162,000 yen | Approx. 168,000 yen | Kameari, close to Ario, enjoys high demand for recent builds and holds firm pricing. |
| Railway Jurisdiction & Direct Access | Tokyo Metro Chiyoda Line (Terminus Station) | JR Joban Line Local Service (Chiyoda Line Direct) | Ayase wins decisively in both securing seats and last-train times. |
| Commercial Scale & Weekend Amenities | Station-internal shops, elevated retail, mid-sized supermarkets | Ario Kameari, extensive shopping streets | Kameari holds the advantage with Ario offering all-day entertainment. |
| Neighborhood Vibe & Nightscape | Municipal housing and residential areas, relatively quiet | Shitamachi charm, Kochikame motifs, vibrant dining districts | The choice comes down to preferring lively energy versus a calm atmosphere. |
| Medical & Childcare Infrastructure | 44 medical facilities around the station | Close to general hospitals (such as Tobu Regional Hospital) | Well-equipped at both stations. Worth noting Adachi/Katsushika benefit policies. |
Definitive Differences in Transportation Access: Commuting Realities of Chiyoda Line Origin Metro "Ayase" vs JR Joban Line Local "Kameari"
In your daily commute to work or school, the convenience of trains is the single most important factor determining your quality of life (QOL). Despite being on the same direct Chiyoda Line route, a decisive difference in operating schedules and riding experience exists between Ayase and Kameari.
The Advantage of Sitting All the Way to Otemachi: The Chiyoda Line Originating Train Service, Ayase Station's Greatest Weapon
The greatest charm of Ayase Station is undoubtedly the abundance of Tokyo Metro Chiyoda Line originating trains starting right from this station. During the morning rush hours (7 AM to 8 AM), originating trains bound for Yoyogi-uehara depart from Ayase every few minutes. By simply lining up on the platform a little early, you can spend your extended journey guaranteed a seat: about 20 minutes to Otemachi Station, about 25 minutes to Kasumigaseki Station, and about 30 minutes to Omotesando Station.
Being freed from the stress of being crushed in packed trains, the time you can spend concentrating on reading, studying for certifications, or gathering information on your smartphone holds immeasurable value for working professionals. Being able to fully leverage the mobility of the Chiyoda Line—connecting to the Yamanote Line at Nishi-nippori, the Marunouchi and Chuo Lines at Shin-ochanomizu, and the Hibiya and Toei Mita Lines at Hibiya—is truly a privilege reserved exclusively for residents of Ayase.
JR Joban Line Local Service at Kameari Station: Realities of Chiyoda Line Through-Service and Fare Rules
In contrast, Kameari Station is a station on the JR East Joban Line, but the green-banded local trains running during daytime and commuting hours generally continue directly onto the Tokyo Metro Chiyoda Line. Therefore, the physical travel time itself—being able to ride from Kameari straight to Otemachi or Akasaka without transfers—differs by only about 2 to 3 minutes compared to Ayase.
However, trains arriving at Kameari Station are already in a packed state with passengers boarding from Abiko, Kashiwa, and Matsudo. Securing a seat during the morning peak hours is virtually impossible. Furthermore, because the route spans both JR and Metro lines, commuter pass and regular fares are calculated as a combined sum of the JR base fare plus the Metro fare. You must keep in mind that this creates a difference in your monthly transportation subsidy limits and your private travel expenses to and from the city center.
Last Train Times and Delay Resilience: Recovery Power During Suspension of Operations Across Kita-Senju, Ayase, and Kameari
The peace of mind when returning home late at night is also not to be overlooked. The final Chiyoda Line train departing from Otemachi Station toward Ayase runs as late as 12:20 AM, allowing you to return home without panic even if you stay late in the city center for overtime work or dinners. On the other hand, the final JR through-train going all the way to Kameari finishes about 20 minutes earlier than this.
Should you miss the last train bound for Kameari late at night and end up taking one stopping at Ayase, the distance from Ayase Station to Kameari Station is about a 25 to 30-minute walk, or just over the base taxi fare (around 1,000 yen). While it is not an impossible distance to walk, Ayase takes the crown for your daily commuting flow home. Even in the event of accidents causing injury or timetable disruptions, Ayase Station provides the reassurance of minimizing the risk of being unable to return from the city center, thanks to the Chiyoda Line's capability to quickly resume turnaround operations.
Realistic Comparison of Shopping, Dining, and Daily Life Lines: The Overwhelming Commercial Power of Ario Kameari vs. Ayase's Elevated Under-Track and Community-Focused Supermarkets
When it comes to picking up groceries on the way home from work on weekdays or spending your weekends, there is a clear difference in personality between the commercial environments of both stations. The neighborhood you should choose depends entirely on whether your lifestyle leans toward "wanting to enjoy shopping and movies within the town on weekends" or "wanting to finish shopping quickly along your commute route on weekdays."
Kameari's Overwhelming Flagship "Ario Kameari" and Abundant Shopping Streets
An indispensable element when discussing Kameari's living environment is "Ario Kameari," a large-scale complex commercial facility located about a 5-minute walk from the South Exit. In addition to Ito-Yokado as its core anchor store, it brings together approximately 130 specialty shops, including MOVIX Kameari (a cinema complex), Uniqlo, Loft, MUJI, Akachan Honpo, various interior and apparel shops, and a large food court.
The convenience of completing your weekend shopping, entertainment, and dining locally without having to head into central Tokyo is Kameari's greatest strong point. Furthermore, multiple shopping streets, led by the Kameari Ginza Shopping Street (You Road), extend in a fan-like shape around the station, packed with traditional side-dish shops, butcher shops, lively bakeries, and privately-run izakayas. The entire town overflows with the warm, human touch of a historic shitamachi (downtown) district, making daily strolls genuinely enjoyable.
Ayase Station Area Grocery Shopping Routes: M'av Ayase, Tokyu Store, Big-A
In contrast, Ayase Station shines with a practicality-first commercial layout that takes full advantage of the elevated under-track space and station plaza. The under-track commercial facility "M'av Ayase," which connects directly to the station, compactly consolidates drugstores, cafes, and restaurants. Under the station tracks sits the "Tokyu Store Ayase Branch," open until 10:00 PM, and on the East Exit side stands the large general supermarket "Ito-Yokado Ayase Branch," whose food floor is also open until 10:00 PM, allowing you to finish procuring groceries within dozens of steps of exiting the station gates.
Furthermore, walking a little further from the station reveals scattered discount supermarkets like the "Big-A Adachi Ayase Branch" and specialty shops where you can purchase commercial-grade ingredients at low prices. While it may lack movie theaters and large fashion buildings, it establishes an extremely efficient living route for busy single residents in terms of allowing you to shop for reasonable home-cooking ingredients late at night without making unnecessary detours on your way home from work.
Dining Out Situation for Single Residents: Chain Restaurants & Under-Track Izakayas vs. Shitamachi-Vibe Drinking Districts
Let's also compare the dining-out environment for single residents who do not cook very often. Around Ayase Station, standard chain restaurants such as Hidakaya, Matsuya, Yoshinoya, Gyoza no Ohsho, and McDonald's are comprehensively covered along the station's elevated under-track area. There are many counter-centric eateries where even a single person can enter without hesitation, making them ideal for a lifestyle of quickly finishing dinner and heading home.
On the other hand, Kameari Station features not only chain restaurants but also a multitude of unique, renowned establishments known as a ramen battleground, alongside privately-run signature popular taverns and yakitori shops in both the North and South exits. There is an atmospheric charm that makes you want to drop by casually on the night before a holiday and enjoy pleasant conversations at a comfortable distance with regular patrons and owners. For those who want to treat dining out not merely as nutritional replenishment but as part of the enjoyment of life, Kameari's deep dining districts will surely appear exceptionally attractive.
In-Depth Verification of Safety, Nighttime Walking Security, and Ground Hazards: The Truth Revealed by Official Data
When hearing names like Adachi City or Katsushika City, some clients express concern based on outdated information found on the internet, asking if safety might be an issue. However, a careful examination of recent Tokyo Metropolitan Police Department crime statistics and administrative crime-prevention measures reveals that the actual reality is quite different.
Tokyo Metropolitan Police Department Crime Information Map and Crime Prevention Initiatives in Adachi and Katsushika Cities
According to the "Number of Recognized Cases by Town/Block, Crime Type, and Modus Operandi in Municipalities" published by the Tokyo Metropolitan Police Department, the number of violent crimes in the areas surrounding Ayase Station (Ayase 1-chome to 4-chome) and Kameari Station (Kameari 3-chome and 5-chome) is extremely low, maintaining a calm level compared to other major station areas in Tokyo's 23 wards. Adachi City has long implemented the "Beautiful Windows Movement," promoting patrols by blue-light crime-prevention cars and the strategic installation of security cameras. Street crimes have plummeted over the past 10 years.
The majority of minor crimes that do occur are "bicycle thefts" around the station and "verbal altercations on the street." These can be sufficiently avoided with basic self-defense measures, such as securely locking bicycles at parking lots and avoiding nightlife and touting areas late at night. Even for single women living alone, there is no need for excessive anxiety as long as you choose a route home from the station that passes along brightly lit, major thoroughfares.
Checking Walking Alone at Night: Street Illuminosity and Commute Routes Around the Ayase and Nakagawa Rivers
The actual atmosphere of nighttime walking has area-specific points to watch out for. In the case of Ayase Station, the north exit area toward Higashi-Ayase Park and along the elevated tracks maintains a good presence of people, with residents running or walking even at night. However, heading toward the Ayase River side or entering the narrow alleys of the west exit, streetlamp spacing widens somewhat, and noticeable dark spots exist. When searching for a property, it is important to walk the shortest route from the station after sunset to check whether it is a road with sufficiently bright streetlamps and sidewalks.
For Kameari Station, the south exit features constant pedestrian traffic past 10:00 PM, centered around the traffic flow heading toward Ario Kameari. The streetlights in the shopping district are also well-maintained, making it extremely bright and with excellent visibility. However, the residential areas heading toward the Nakagawa Water Gate on the north exit side and the alleys one block back from Ring Road Route 7 fall completely silent, so those who frequently return home late at night will greatly increase their peace of mind by prioritizing properties on the south exit side.
Ministry of Land, Infrastructure, Transport and Tourism Hazard Information: Liquefaction Tendency and Maximum 3.0m to 5.0m Flood Inundation Projections
More than crime, as a licensed real estate transaction specialist, the natural disaster hazards such as water damage are what we urge you to pay attention to. According to official data from the Ministry of Land, Infrastructure, Transport and Tourism, the topography of the Ayase and Kameari areas belongs to "deltas and coastal lowlands," and the liquefaction tendency in the event of an earthquake is designated as "prone to liquefaction."
Furthermore, flood inundation projection maps assuming the overflow of the Arakawa and Nakagawa river systems predict inundation depths of "a maximum of 3.0m to less than 5.0m" across wide areas of both districts. This is a level of flooding that reaches the eaves of the second floor. Therefore, when signing a lease agreement, please strictly check the following points:
- Avoid first-floor units and choose floors on the second floor or higher whenever possible.
- Confirm whether electrical rooms and power receiving/transforming equipment are located above ground or near the rooftop rather than in the basement.
- Understand in advance the evacuation routes to designated emergency evacuation sites (high ground or designated flood evacuation buildings) specified by local governments (Adachi City and Katsushika City).
This hazard information does not mean you should "never live there," but rather should be viewed as an indicator to "choose properties equipped with safe floor heights and evacuation routes" based on correct knowledge.
4 Steps to Flawless House Hunting & Layout-Specific Rent Simulations
Now that you understand the characteristics of Ayase and Kameari, let's move on to the practical steps and cost simulations needed to secure an apartment you'll truly be satisfied with. Anticipating and clearing potential trouble spots in real estate transactions is the golden rule of success.
Initial Cost Simulation for Singles (Rent 75,000 JPY vs. 70,000 JPY)
The general guideline for initial costs in a rental contract is about 4.5 to 5 months' worth of rent. Let's compare the total contract costs for a standard Ayase 1K apartment (Rent: 75,000 JPY) versus a Kameari 1K apartment (Rent: 70,000 JPY).
- Ayase (Rent: 75,000 JPY + Maintenance Fee: 8,000 JPY): Total initial costs approx. 370,000 JPY to 410,000 JPY (includes advance rent, 1 month deposit, 1 month key money, agency fee, guarantor fee, fire insurance, etc.)
- Kameari (Rent: 70,000 JPY + Maintenance Fee: 7,000 JPY): Total initial costs approx. 340,000 JPY to 380,000 JPY
- Total Cost Difference over 2 Years: Rent difference of 5,000 JPY/month x 24 months = 120,000 JPY + renewal fee difference = Kameari is about 125,000 JPY to 130,000 JPY cheaper.
This calculates out to a difference of about 130,000 JPY over two years. The deciding factor is whether you view this price difference as an investment in Ayase for "seated commuting and later last trains," or if you prefer to wisely save that amount in Kameari for "savings, hobbies, and shopping."
The Realistic Solution for Couples and Shared Living (1LDK to 2LDK) Screening & Living Costs
For couples living together or dual-income DINKS, the volume zone in both Ayase and Kameari is 110,000 to 130,000 JPY for 1LDK (approx. 40 sqm) and 150,000 to 170,000 JPY for 2LDK (approx. 55 sqm). Rental screening typically looks for a "monthly income of about 3x the rent (combined household income)," so if you are renting a 150,000 JPY property, a net monthly income of around 450,000 JPY is one baseline to pass.
Both Adachi and Katsushika wards feature well-developed licensed daycare centers and pediatric clinics. According to Ministry of Land, Infrastructure, Transport and Tourism data, there are 4 licensed daycare facilities and 44 medical institutions operating within walking distance of Ayase Station alone, providing peace of mind for dual-income households with children. If one partner commutes toward Otemachi/Hibiya and the other toward Ueno/Tokyo/Shinagawa, Ayase and Kameari serve as exceptional compromises due to easy transfers at Kita-Senju Station to the Hibiya Line, Ueno-Tokyo Line, Tsukuba Express, and more.

Frequently Asked Questions (FAQ)
QCan you walk between Ayase Station and Kameari Station? Is it possible to commute between them by bicycle?
AThe straight-line distance between the two stations is approximately 2.2 km, taking about 25 to 30 minutes on foot, or around 8 to 10 minutes by bicycle. Because the terrain is mostly flat, cycling is extremely comfortable. This allows for a flexible lifestyle setup, such as living in Ayase and cycling over to Ario Kameari for weekend shopping, or living in Kameari and cycling to Ayase Station to catch a departing train on the Chiyoda Line.
QIf I take a train from Kameari Station that connects directly onto the Chiyoda Line, will my commuter pass or fare be more expensive?
ABecause this involves through-service operations between JR East and Tokyo Metro, fares are higher compared to trips starting and ending at Ayase. For example, for a 1-month commuter pass to Otemachi Station, the cost from Ayase to Otemachi is 8,680 yen (Tokyo Metro fare only), whereas from Kameari to Otemachi it is 14,060 yen (JR + Tokyo Metro joint commuter pass), resulting in a difference of a little over 5,000 yen per month (5,380 yen). If your company fully reimburses your transportation expenses, there is no out-of-pocket cost, but those who have to cover their own travel expenses should keep this in mind.
QI am concerned about the risk of flooding from the Arakawa and Nakagawa Rivers. What specific types of properties should I avoid when choosing a place?
According to Ministry of Land, Infrastructure, Transport and Tourism hazard maps, projected flooding can reach anywhere from 3.0m to under 5.0m, so it is wise to avoid "first-floor units in wooden apartment buildings" and "semi-basement units." You can dramatically increase the safety of your belongings and your life by choosing a reinforced concrete (RC) or steel-framed reinforced concrete (SRC) apartment building and selecting a floor on the 3rd floor or higher, which sits above the projected flood level. Additionally, checking whether water storage tanks and entrance flood barriers are installed is an effective self-defense measure.
