Right after the Expo ended, a large number of EV buses were lined up in the Osaka City Bus Minato Depot parking lot. In September, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) issued a total inspection order. Concerns revealed by multiple sources How will EVMJ respond to this pile of problems? Our site sent a set of questions to the company regarding: The reality behind the suspension of dealings with Meimon Taiyo Ferry, Whether storage fees were charged to Osaka Metro, and The status of defects in the replaced brake hoses. Regarding the first point, the suspension of dealings with Meimon Taiyo Ferry, EVMJ responded as follows: “Regarding Meimon Taiyo Ferry, as stated in their December 28, 2023, information, the company has temporarily stopped accepting all EV vehicles, not only ours. Therefore, we are currently using other ferry companies to transport vehicles. At present, we have not been notified of any suspension concerning departure or arrival ports for vehicle transport.” Indeed, Meimon Taiyo Ferry stopped unmanned transport of EV vehicles from January 1, 2024, but manned transport remains unaffected. The EVMJ EV bus delivered to Osaka Metro, the “Aichuwa E1,” caused a ferry delay in March 2025 during a manned transport. Internal company emails from March 7 indicate awareness of statements such as: “Meimon Taiyo Ferry claims they do not want to carry us due to repeated delays and cancellations. Apologies and requests to the ferry company are necessary.” Regarding the second point, whether storage fees were charged to Osaka Metro, EVMJ said: “This is not an official statement from us, and we deny it. Regarding costs, due to negotiations and transaction conditions with the customer, we refrain from commenting.” However, the reporter obtained an invoice issued by EVMJ to Osaka Metro in December. It listed: “Izumi-Otsu parking lot fee (2 months) 600 tsubo (Nov 1–Dec 31)” and the amount roughly matches what was reported. Finally, regarding the status of defects in the replaced brake hoses, EVMJ stated: “Regarding the recall, we are proceeding with replacement work while consulting with each operator. At present, there have been no reports of defects during implementation.” Yet multiple EVMJ sources interviewed disclosed: “Nearly 20% of the brake hoses sent from WISDOM have defects and cannot be safely used as replacement parts for the recall.” Osaka Metro, the owner of the EV buses, plans to relocate the stored large buses to another site by the end of December. It seems they will not send the buses back to EVMJ for reinspection, and a decision has been made to completely halt their use. Given EVMJ’s precarious position, it is hard to imagine any company purchasing their buses in the future. Though the location may change, the day a graveyard of EV buses is created might arrive sooner than expected.
