Shin-Koenji Store was one of three stores — along with Kanda Ogawamachi Store and Shinjuku 1-chome Store — that ended 24-hour operation and switched to shortened hours on April 17, 2026. This time, Shin-Koenji Store alone has returned to 24-hour operation about 28 days later. The remaining two stores continue to operate shortened hours from 9 AM to 10 PM as of today.
