Editorial interest 84/100 Selection signal · not a rating of the site

A Japanese calculator that compares a household’s propane-gas bill and usage with public regional price data.

Landing page captured for the 2026-09-07 issue.

Field notes

The calculator asks for a prefecture, housing category, monthly bill, and cubic-meter usage, with basic charge as an optional input. Its reference figures are attributed to monthly prefectural retail-price data from Japan’s Petroleum Information Center; the page gives a 9,713-yen 10-cubic-meter national simple average for the June 2026 survey. The surrounding guides separate questions for homeowners and renters, since the latter may not be able to change suppliers independently.
