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.
