Retailer observations on October 20, 2026
BOOK1: Yodobashi
The directly read listing matched the ISBN and ¥5,500 price and identified Japanese as the language. It showed preorder acceptance ended. Check the current Yodobashi listing.
BOOK1: Rakuten Books
The directly read listing matched the ISBN and ¥5,500 price and accepted preorders at that check. Its delivery wording allowed arrival on or after publication and possibly later. Check the current Rakuten BOOK1 listing.
BOOK2: Rakuten Books
Matching product details appeared in indexed retailer text, including preorder wording. The direct listing was not separately inspected. Treat its current ordering status as unverified here. Open the Rakuten BOOK2 listing.
No retailer stock or delivery status was established for BOOK3. Use its publisher ISBN to check the seller you choose. None of these observations confirms shipping outside Japan.
Understand the total before paying
Three separate volumes at list price add up to ¥16,500. Shipping, proxy handling and destination taxes can increase an import total. No exchange rate or overseas suggested price has been researched for this guide.
Ask the seller whether the order is a single volume or a seller-created bundle. Do not infer an official collector’s box, preorder bonus or signed edition from a bundled listing; no such edition was confirmed in the official records reviewed.
Read cancellation and return conditions before a preorder or proxy purchase. Book condition, packaging and damage procedures are seller questions. The publication date cannot answer them.
