Japanese publishing giant Shueisha Inc. has suffered significant financial disruption after a 32-year-old woman from Osaka allegedly exploited its online ordering systems to place thousands of fraudulent orders totaling approximately 4.3 billion yen, or roughly $27.2 million.
Mayu Yoshida, a restaurant worker, was arrested this week following a year-long investigation into the scheme. Police allege she created 238 separate accounts to place more than 2,000 orders for manga merchandise between 2024 and 2025, with no intention of paying for the items.
Yoshida exploited two payment mechanisms common in Japanese e-commerce. She frequently selected convenience store prepayment, a system that allows buyers to reserve items and pay later at a physical kiosk. When payment was not made within the allotted window, the orders were automatically cancelled — but not before Shueisha had incurred processing and logistical costs. In other instances, she chose cash-on-delivery and simply refused the packages upon arrival.
Shueisha estimates the direct financial loss from fees and handling at approximately 7.5 million yen, or about $47,000. The company also noted indirect damage, including lost sales opportunities when high-demand items were listed as out of stock due to her reservations.
Confronted with the evidence, Yoshida admitted to placing the orders but denied any grudge against the publisher. She told investigators the activity provided a sense of satisfaction and stress relief, describing the act of securing items before they sold out as refreshing.
The case highlights vulnerabilities in retail systems that prioritize customer convenience, particularly in markets where cash-based payment options remain widespread. Authorities have not disclosed whether Yoshida faces formal charges or what penalties may apply, but the arrest underscores growing scrutiny of digital fraud tactics that weaponize standard commercial infrastructure.
Shueisha, one of Japan’s largest manga publishers, has not announced changes to its ordering policies in response to the incident.
