Summary

Upopoy will open on Monday August 10, 2026 and on six additional special dates through February 2027, overriding its usual Monday closure for peak visitor demand.

Upopoy announced on August 7, 2026 that it will hold a special opening day on Monday, August 10, 2026, along with a series of additional special dates through February 2027, overriding its usual Monday closure.

Special opening dates

  • Monday, August 10, 2026.
  • Monday, August 24, 2026.
  • Thursday, September 24, 2026.
  • Monday, October 19, 2026.
  • Monday, November 2, 2026.

Why it matters

Publishing a full multi-month calendar of extra opening days – rather than case-by-case notices – gives travel agencies and independent visitors a reliable planning window into next winter. It also confirms that Upopoy views strategic Monday openings as a permanent tool rather than a one-off summer measure.

For international readers

Standard opening hours during this window are 9:00 to 18:00. Travellers combining Upopoy with a broader Hokkaido tour can now schedule the visit on days that would previously have been closed.
