Emergency food for a family of four under 10,000 yen: how to choose and the conclusion on 24-pack shelf-stable rice
Updated Oct 16, 2026・price checked Oct 16, 2026
When the fridge contents start to spoil during a power outage and you need to figure out how to feed a family of four for 3 days, the rice you have at home won't be enough. If you don't calculate the amount per meal and the number of packs beforehand, you'll end up buying more later.
Yuuen's pick
Conclusion: Wa-uke Tokumori Gohan 300g x 24 packs can serve as the core for securing staple food at room temperature, but you should plan to add side dishes, soup, and drinking water separately.

Before you buy
Check the product page for the expiration date at time of delivery, the total weight of 300g x 24 packs, and whether it supports both microwave and hot-water-bath cooking methods.
How to choose
- Calculate by number of people x number of days x number of meals
For a family of four to get through 3 days, 3 meals x 4 people x 3 days = 36 meals is a rough guide. When you count side dishes and soup along with packaged rice, you'll find one set isn't enough.
Source: Ministry of Agriculture, Forestry and Fisheries - Check whether it can be stored at room temperature
Items requiring freezing or refrigeration can't be used during a power outage. Choose mainly packaged rice, canned goods, and dried foods that can be kept at room temperature.
- Stock staples and side dishes separately
Trying to fit staples, side dishes, and soup all into one set makes it more expensive. Buying rice in bulk bags and adding soup and side dishes separately in small amounts keeps overall costs down.
- Cooking method and water usage
Types that require a hot-water bath or reconstituting with water consume water. Keeping a larger supply of packaged rice that can be eaten as-is during water outages reduces water consumption.
- Managing storage space and expiration dates
Items delivered in boxes, such as 24-packs, take up storage space. Decide on storage location assuming a rolling stock system where you record expiration dates and rotate stock through everyday meals.
Who it's for / who it isn't for
Who it's for- Families of four who want to stock staple rice in bulk at room temperature
- People who want to heat it in a microwave or hot-water bath and use it for everyday meals too
- People who want to keep costs down by planning to prepare side dishes and soup separately
Who it isn't for- Not suitable for those who want side dishes included in one set as well. Consider combining two 2-person sets instead.
- Not suitable for those who want everything including water in a single set. Consider a set that includes water.
Comparison
| Item | Price | Contents/number of meals | Storage method | Cooking method | Why not this one |
|---|---|---|---|---|---|
| Wa-uke Tokumori Gohan 24 packs | 6,126 yen | 300g x 24 packs (rice only) | Room temperature storage | Heat in microwave or hot-water bath | — |
| Onisi emergency food 18-meal set (for 2 people) | 7,649 yen | 18 meals (3-day supply x 2 people) | 5-year shelf life | Reconstitute with hot water/water, or eat as-is | This is a 3-day set for 2 people, so it is not suitable as the stockpile amount for a family of 4. |
| Disaster food set, 18 meals (for 2 people) | 6,980 yen | 18 meals (3-day supply x 2 people) | 5-year shelf life | Reconstitute with water or hot water | This is also a 3-day set for 2 people, so it is not suitable for a family of 4. |
| Emergency Food Set A (1 person, includes water) | 5,390 yen | 3 days' worth + 2.5L water (equivalent to 1 person) | Stores for 5-10 years | Reconstitute with water / ready to eat as is | Since this is a 1-person set that includes water, it is not suitable as the stockpile amount for a family of 4. |

Why this one
At 6,126 yen for a pack of 24, each item costs about 255 yen. Since 300g is close to the standard amount for one adult meal, this works out to enough for 2 days for a family of 4 if only rice is eaten.
Since this is aseptically packaged cooked rice, it can be stored at room temperature, and even during a power outage it can be eaten warmed by hot water bath or microwave. It also requires less storage space than stockpiles that need freezing or refrigeration.
It can be heated either in a microwave or by hot water bath, so you can choose the cooking method depending on whether power is available. It can also be used in everyday meals, making it suitable for rolling stock, where you consume and replace stock while watching expiration dates.
Downsides
- Side dishes and soup are not included and need to be prepared separately.
- 24 pieces fall short of the 36 meals needed for 3 days for a family of 4, leaving a shortfall of 12 meals.
- Even with room-temperature storage, expiration dates vary by product, so you need to check the date at the time it arrives.
If you're in a different situation
Onisi's 18-meal emergency food set bundles 3 days' worth for 2 people, so if you get 2 sets, you'll have staple food and side dishes for 4 people.
This combines water that stores for 10 years with food that stores for 5 years, saving you the trouble of planning water stockpiles separately.

FAQ
- Can emergency food for a family of 4 be fully covered for 10,000 yen or less?
- Not entirely. Options under 10,000 yen are mainly for 1-2 people, and there are almost no sets that cover both food and water for 4 people together.
- How many days' worth of emergency food should be prepared?
- A minimum of 3 days' worth is the guideline. In the 72 hours after a disaster occurs, rescue operations are prioritized, and relief supplies typically don't arrive in full force until the 4th day or later.
- Does water need to be prepared separately from emergency food?
- Yes. The guideline is 3 liters of drinking water per person per day, so a family of 4 would need about 36 liters for 3 days, which should be planned separately from food.
