Find out the adequate stockpiling for you

Based on information such as the number of family members, your and your family's sex and age group, and your housing environment, a list of required stockpile items and quantities is displayed. You can purchase each item on an e-commerce site, or print/save the list on your device and use it as a shopping list.

Based on the list of stockpile items and quantities shown in "Find out the adequate stockpiling for you," this feature lets you check your actual stockpile status.
By entering the quantity and expiration date for each item, you can record and update your stockpile status and check how sufficient your stockpile is against the recommended amount.

After checking your stockpile status, you can answer questions to calculate your stockpile score and share the result on social media.
