When deciding on a moving date in Japan, "Daian" is often the first day that comes to mind. As the luckiest day in Rokuyo (the traditional calendar system), Daian (たいあん) translates to "great peace." True to its name, it is a special day where every time slot is considered auspicious. The fact that Daian is chosen for all kinds of "new beginnings"—from weddings and business launches to car deliveries—shows just how much peace of mind it offers.

1. What is Daian (たいあん)?
Many people only notice the characters on Japanese calendars when the moving season starts, wondering what "Daian" actually means. These terms are part of "Rokuyo (六曜)," a calendar system originating from ancient Chinese time divination that became popular in Japan during the Edo period. Among the six days, Daian is special. Unlike other days where luck shifts (such as lucky in the morning but unlucky in the afternoon), Daian is auspicious from morning until night. Meaning "great peace," it is easy to see why it is considered the ideal day to start a new life.
2. The Six Rokuyo Days and Their Suitability for Moving
In addition to Daian, there are five other days in the Rokuyo system. Each day has specific time windows that are considered lucky or unlucky, which can subtly affect when you should start your moving tasks. Refer to the table below for details.
| Rokuyo | Pronunciation | Meaning & Characteristics | Moving Suitability |
|---|---|---|---|
| 大安 (Daian) | Tai-an | All-day great luck. The most auspicious day for starting any new venture. | ◎ Excellent (Best) |
| 友引 (Tomobiki) | Tomo-biki | Draws friends into good fortune. Lucky all day except at noon. | ○ Good |
| 先勝 (Sensho) | Sen-sho | Lucky in the morning, unlucky in the afternoon. Best for early starts. | △ Morning Only |
| 先負 (Senbu) | Sen-pu | Unlucky in the morning, lucky in the afternoon. Best for afternoon starts. | △ Afternoon Only |
| 赤口 (Shakko) | Shak-ko | Unlucky all day except at noon. Extra caution is advised regarding fire and accidents. | ▲ Avoid if possible |
| 仏滅 (Butsumetsu) | Butsu-metsu | Unlucky all day. Some interpret it as a clean slate for starting fresh. | × Generally avoided |
The Hidden Benefits of Choosing "Butsumetsu"
If you do not mind traditional taboos, moving on Butsumetsu is highly economical. Because demand drops significantly, it is much easier to negotiate and get 20% to 30% discounts compared to Daian. Booking dates are also much easier to secure. Reinvesting those savings into initial costs needed for renting in Tokyo or purchasing new furniture is a highly practical way to start your new life.
3. The Benefits of Moving on a Daian Day
Surrounded by packed cardboard boxes, arriving at an unfamiliar train station, and dealing with tasks like setting up lifelines like electricity, gas, and water before and after moving—moving is a hectic process. In the midst of all this busyness, knowing that "today is Daian" brings a strange sense of calm. Believing in luck is less about superstition and more about stabilizing your state of mind.
- Mental Peace of Mind: Stepping into your new home on an auspicious day brings a positive feeling. It helps you focus on your new life with a clear mind, free from unnecessary worries.
- Reassuring Family Members: Even if you do not worry about luck, parents or relatives might worry about your schedule. Telling them "I chose a Daian day" keeps everyone happy and ensures they support your move with peace of mind.

4. Estimated Moving Costs on Daian Days
The day itself does not increase the fee. Rather, high demand on those specific days means moving companies are booked out, making discounts harder to get. Check the price estimates below to balance your budget and preferred schedule:
| Date Combination | Price Trend | Booking Difficulty |
|---|---|---|
| Daian × Weekend × Mar–Apr | 1.5 to 2+ times normal rate | ⚠️ Extreme Competition (Book 3–4+ months ahead) |
| Daian × Weekend (Regular Season) | 1.2 to 1.5 times normal rate | ⚠️ High Demand (Book 1.5–2 months ahead) |
| Daian × Weekday | Standard rate to 1.2x | ✅ Relatively easy to secure |
| Butsumetsu × Weekday | May be 20%–30% cheaper | ✅ Good availability / Easier to negotiate |

6. 5 Key Tips for a Successful Daian Move
Once you have chosen a good day, you want to make sure the details are handled smoothly. Simulating the moving day schedule in advance prevents last-minute stress.
- Request Estimates Early (Even Provisional): Many companies allow you to hold a slot tentatively. Even if your apartment details are not finalized, securing your preferred date early is key. Getting quotes from multiple companies gives you more options.
- Choose a "Morning Slot" to Secure Extra Time: Although Daian is auspicious all day, a morning slot is the most practical choice. The truck arrives on time, allowing you to focus on unpacking by the evening without inheriting delays from previous jobs.
- Introduce Yourself to Neighbors on the Move Day: Greeting neighbors with a small gift on the day you move in makes a positive impression. Mentioning that you moved in on a Daian day can be a great conversation starter.
- Purify the Empty Space with Morishio (盛り塩): Placing small cone-shaped piles of salt in the rooms before carrying in your belongings makes the space feel truly yours. It takes less than five minutes.
- Create a Narrative Starting from the "Contract Signing Date": Signing your lease contract on a Daian day connects the key handover and moving day into a single story of good fortune. Before signing, understanding the market rates of security deposits (shikikin) and key money (reikin) and tips to keep them low will help you start your new life with confidence.
