Reasons to choose the esona 1-person backpack disaster kit, a disaster prep set under 30,000 yen for single-person households
Updated Oct 16, 2026・price checked Oct 16, 2026
When an earthquake happens in a single-person household, how much water and food you can carry out depends entirely on your own judgment. A disaster kit should be chosen based on whether the amount of water and the contents of the emergency food are actually enough for daily life, rather than the number of items included. Even under the 30,000 yen condition, there is a notable difference between products that clearly state their contents and those that do not.
Yuuen's pick
If you are choosing a disaster prep set for a single-person household under 30,000 yen, the esona 1-person disaster set offers a good balance between content supervised by a disaster prevention specialist and price, but since the included water and food do not reach a 3-day supply, choose it on the premise that you will prepare the rest separately.

Before you buy
Please check the product page before purchasing for the expiration dates of the bread and preserved water, and whether the 5L×2 water bags are actually usable for water supply.
How to choose
- The standard is 3 liters of water per person per day
For a 3-day supply, 9 liters per person are needed, but this is not an amount that fits in one backpack. Treat the water in the set as being for initial response only, and stockpile the rest separately at home.
Source: Fire and Disaster Management Agency - Emergency food is calculated as 3 meals per day multiplied by the number of days
For a 3-day supply, 9 meals is the standard. Check the number of meals in the set, and supplement any shortfall with canned goods or retort pouch foods you normally eat, to make management easier.
Source: Ministry of Agriculture, Forestry and Fisheries - Always check the weight of the backpack
When living alone, you will carry the bag out and evacuate by yourself. Around 3kg is manageable even for women, but anything over 5kg becomes difficult to carry out.
- Count the number of uses for the portable toilet
When water supply is cut off, regular toilets cannot be used. Assume about 5 uses per day and check whether the number included in the set is sufficient.
- Note the shelf life and replacement timing
Water and food have a shelf life. Check the number of years at the time of purchase, and record the replacement timing on a calendar so you can maintain your stock without gaps.
Who it's for / who it isn't for
Who it's for- People living alone who are preparing disaster supplies for the first time
- People looking for a disaster prevention specialist-supervised set in the 10,000 yen range
- People looking for a lightweight backpack that can be placed by the entrance or in a corner of a room
Who it isn't for- Not suitable for those living with 2 or more people. Please consider a 2-person set instead.
- Not suitable for those who want a single set to cover a full 3-day supply of water and food alone.

Why this one
At 14,300 yen, this complete 1-person backpack set supervised by a bosaishi is more than 4,000 yen cheaper than the 19,200 yen and 18,700 yen 1-person sets.
Comes with 500ml x 3 bottles of 5-year preserved water, securing 1.5 liters of water immediately after a disaster. This falls short of the 9-liter guideline for 3 days, so an additional 7.5 liters needs to be prepared separately.
Contains 1 each of plain, chocolate, and maple bread, 3 total. This is not enough for the guideline of 3 meals a day, but it secures food to get through the first day.
The main unit weighs about 3,070g, a manageable weight for someone living alone to carry on their back and evacuate by themselves.
Downsides
- The preserved water is only 1.5 liters, falling short of the 9-liter guideline for 3 days per person. Additional drinking water needs to be prepared separately.
- The emergency food is 3 pieces of bread, far short of the 3-day/9-meal guideline. Please add regular foods such as canned goods or hardtack.
- The expiration date of the bread is not clearly stated in the set description, so you need to check the product page to see how much shelf life remains upon arrival.

FAQ
- Is a 1-person disaster prevention set enough for someone living alone?
- A 1-person set covers the basic equipment, but water and food fall short of the 3-day guideline, so additions are needed.
- How much of a disaster prevention set can be bought for under 30,000 yen?
- For 10,000 to 20,000 yen range, you can purchase sets that include a complete backpack plus items like a portable toilet and light. Generally, the higher the price, the more items and the longer the warranty period.
- How often do disaster prevention sets need to be replaced?
- The shelf life of water and food serves as a guideline. Since this set's preserved water is labeled with a 5-year shelf life, please check the contents every 5 years.
