Category guidance and candidate extraction policy
- Items are organized from Rakuten Ichiba Item API data using category fit, page context, review count, review average, and downgrade rules for over-sized or off-context items.
- Prices, stock, capacity, and specifications can change. Confirm the latest details on Rakuten before purchasing.
What to check first for this condition
- Public-reference baseline: Japanese agencies commonly recommend 3 liters of drinking water per person per day and at least 3 days of household supplies.
- Site-defined baseline: portable toilets are estimated at 5 uses per person per day, and power banks at 10000mAh or more for initial smartphone charging.
- 10000mAh and 300Wh are not public-agency thresholds; they are site-defined criteria for communication and minimum blackout support.
