Where these numbers come from
Editions, volumes and ISBNs come from the National Diet Library of Japan's bibliographic records, retrieved 2026-07-28 (214 records matched). Where the library record is ambiguous — an imprint with no series title, a volume count that could be partial — this page says so instead of guessing.
Cover prices at publication and imprint names come from openBD, the free Japanese book-metadata API, and are quoted only for the editions where openBD actually returns one. The rest print no price at all rather than an estimate.
What this page deliberately does not print. Page counts and trim sizes. Earlier versions of this page showed both. On 2 August 2026 we asked openBD for all 57 ISBNs listed here: it holds a record for 30 of them, and of those 30 it returns a page count for zero and a physical measurement for zero. The National Diet Library, for its part, records manga of this vintage as “1冊 ; 18cm” — one volume, eighteen centimetres — with no page count and no format name at all. So there was no source behind any of those figures, and they have been removed rather than dressed up. If a number is missing from this page, that is the reason.
Current prices and availability were measured on 2026-08-16 by looking up every ISBN against Japanese retail: 8 of 57 volumes are stocked new, 41 of 57 returned a used listing, and 34 of 57 had a listing that was both in stock and honestly priced.
On the missing 7 volumes. 21 listings were excluded because they carried a placeholder price clustered around ¥30,000 — the same figure appearing on different books, different volumes and different publishers from one family of used-book chains. That is not a market price; it is what a shop puts on a listing it cannot delete but cannot fulfil. Counting those as "available" would have made this page look better and be wrong.
Two kinds of buy link. 52 of 57 volumes link to a shop-comparison page, which keeps working after any one copy sells. The rest link to a single used copy and will break the moment somebody buys it. Both are marked as such next to the volume.
Shipping, payment and import tax are the one part of this page no robot measured. They were read by hand on 2026-08-04 from Rakuten's own pages — the Rakuten Ichiba help centre for the seven-country list, and Rakuten Global Express's country guides, its published list of the countries it delivers to, and its fee pages for the tax rates, the lines, the American minimum and Norway's absence — and every figure was read twice, by different means, before being printed. Where Rakuten publishes no rate, as with France, this page prints none rather than guessing one. An earlier version of this page also said that other forwarders work the same way as Rakuten Global Express, and named two; we had no source for that and have taken it out. An earlier version of this page said that Rakuten Global Express refuses APO, FPO and DPO addresses, and that America was closed to this route altogether; neither survived a second reading of Rakuten’s own pages, and both are gone. An earlier version of this page said that Rakuten Books does not take a foreign card while marketplace shops do. Rakuten Books' own help page says only that there are restrictions on cards issued outside Japan, and that on some items and some orders they cannot be used; for the marketplace half there was no source at all. Both sentences are gone, and the route box above now says what Rakuten says. Re-read 2026-08-08.
Prices change. Used listings are single copies and disappear when someone buys them. Treat every figure here as the cheapest copy that existed on 2026-08-16, not as a standing price.
