Website-wide Maintenance and Service Outage
Due to system infrastructure maintenance, some services on the Otsuka Shokai website will be unavailable from 10:00 PM on Friday, October 23, 2026, to 1:00 PM on Sunday, October 25, 2026. This will affect all content and functions on customers' My Pages, as well as new registrations and logins for Otsuka ID. Maintenance on September 4‑6 and October 9‑12 has already been completed.
Service Resumption of Inquiry Forms and Other Services
We have resumed services such as various inquiry forms, event and seminar registrations, and school applications that were temporarily suspended for security measures, after confirming their safety. The suspension period was from 9:00 to around 11:00 on October 22, 2026, and services are now available as usual. Otsuka Shokai apologizes for any inconvenience caused to users.
