Nippon Shuppan Hanbai Inc. (Nippan) and PubteX Inc. conducted a proof-of-concept experiment to verify whether RF tags can help bookstores achieve both sales maximization and labor-saving store operations, contributing to sustainable bookstore management. The companies announced that the experiment successfully achieved both goals and established reproducible store operations for replenishment and display management. RF tags enable item-level management of books based on detailed sales and inventory data such as when, what, how many, and where. They are therefore attracting attention as a technology for advancing digital transformation in bookstore operations. As of February 18, 2026, PubteX RF tags have been attached to new comic and paperback releases from 13 publishers and are increasingly used in bookstores for loss reduction, sales-floor management, and analysis. Nippan has also been working with industry partners to promote publishing DX and reform toward sustainable publishing distribution. The experiment was conducted at Ayumi BOOKS Suginami supported by Hontasu, a store operated by Nippan. It used PubteX RF tags and sales-floor inventory and sales data obtained from BOOKTRAIL, PubteX’s book traceability system. The test ran for about six months, from August 4, 2025 to January 31, 2026. The target products were new comic releases with RF tags, while the sales of all in-store comic inventory were analyzed. Two hypotheses were tested. First, changing display operations using RF tags would increase sales of new comics. Second, such changes would improve sales of the entire comic category, including backlist titles. During the first half of the test period, the store used its conventional display operations. During the second half, the store changed display operations across the comic sales floor based on data obtained in the first period. The operational changes included: displaying new comics in multiple locations, including both the prime new-release area near
