About the project

A map for the shelf, desk, and bag.

Bungu means stationery. Atlas means that a useful guide should show boundaries as clearly as destinations.

I’m Aki, the editor behind Bungu Atlas. I built this site for US shoppers who encounter Japanese names such as A6, B6 Slim, Weeks, Regular, Passport, and Campus—and need to know which of those labels describe a size, which describe a system, and which describe both.

What you will find

Expect dimensional comparisons, official compatibility notes, language and calendar distinctions, refill-system maps, and buying routes that make sense from the United States.

What you will not find

You will not see invented pen tests, paper-feel claims, or first-person product stories. Unless a future article clearly says otherwise, the products have not been physically tested by Bungu Atlas.
