Before you buy
Before purchasing, check the product page for the expiration date, whether it can be microwaved or heated in hot water, and the amount of ingredients included.
How to choose
- A guideline of 9 meals (3 days' worth) for emergency food
The Ministry of Agriculture, Forestry and Fisheries recommends stockpiling at least 3 days' worth of food for disasters, ideally 1 week's worth. For one person, that's a guideline of 9 to 21 meals.
Source: Ministry of Agriculture, Forestry and Fisheries - Always check if it can be stored at room temperature
If a power outage occurs, freezers become unusable. If you choose only items that can be stored at room temperature as emergency food, you won't have trouble eating even if the power goes out.
- Balance of staple food, soup, and side dishes
Emergency food consisting only of staples leads to unbalanced nutrition. Securing carbohydrates with rice porridge or zosui, and preparing miso soup or side dishes separately, increases meal satisfaction.
- Also check the cooking method
Some items only require adding hot water, while others need a microwave or hot water bath. Considering whether you can secure a heat source beforehand makes it easier to choose.
- Decide on a storage location in advance
Foods that can be stored at room temperature don't take up space in the fridge or freezer. Deciding on a storage spot in advance, such as a corner of a shelf or closet, makes stockpiling easier.
Who it's for / who it isn't for
Who it's for- People living alone who want to secure a rice-based staple food even during a power outage
- People looking for emergency food that can be eaten as-is without heating
- People who want to stock 12 meals with a variety of flavors so they don't get bored
Who it isn't for- Not suitable for those who also want to stock up on soups and side dishes. Consider a miso soup set.
- Not suitable for those looking for a hearty main dish. Consider retort curry.
Comparison
| Item | Price | Number of meals | Cooking method | Why not this one |
|---|---|---|---|---|
| Rice porridge/zosui set | 2,890 yen | 12 meals | Can be prepared by microwave, hot water bath, or eaten at room temperature | — |
| Miso soup set | 2,710 yen | 25 meals | Just add hot water | Consists only of soup, so it's not suitable for stockpiling as a substitute staple food for solo living. |
| Gogo Curry mild | 2,150 yen | 5 meals | Hot water bath or microwave | With only 5 meals included, it's not suitable for stocking several days' worth for solo living. |
| Pork miso soup, 10-meal set | 1,580 yen (shipping not included) | 10 meals | Just add hot water | It's soup only and also requires a separate shipping fee, so it doesn't fit the budget range for someone living alone. |

Why this one
It contains 12 meals for 2890 yen, making the price per meal about 241 yen. Compared to a set of only miso soup or soup, it offers more satisfaction as a staple food, and the price isn't especially high either.
The zosui and okayu made with ingredients and rice are designed to be eaten even at room temperature. They can serve as a staple food to stave off hunger even when electricity or gas is cut off.
Since you can choose a combination of zosui and okayu according to your preference for the 12 meals, it's easier to avoid getting tired of eating the same flavor repeatedly.
Downsides
- It can be eaten at room temperature, but it tastes better when heated, so some cooking effort is still required
- The ingredients included are only those in the okayu/zosui itself, so you'll need to prepare separate side dishes to add vegetables and protein
- The page doesn't specify the exact number of years for the best-before or expiration date, so you'll need to check this at the time of purchase
If you're in a different situation
Amano Foods' 25-meal miso soup set can be stored at room temperature and lets you stock up mainly on soups.
Go Go Curry Mild 5-meal set can be poured over rice to serve as a main dish, but you'll need to separately stock rice.
