About

Japan by the Numbers is run by a Japan resident based in Hakodate, Hokkaido. It's the English-language sister of Shirein, a Japanese blog that compares prices for everyday purchases.

How we check prices

• Every price comes from the provider's own page, and we show the date we checked it.
• We do the math ourselves (per day, per person, total) and show how we got the number.
• If we haven't used a product, we say so. We don't invent reviews or ratings.
