I visited on a weekday in May 2026. I booked on the day because I was worried about the weather and my health, but I was still able to buy tickets cheaper than at the counter, which was a great help. Upon entry, you show a QR code for each person, but if you only play in the free areas of the park, you don't need to use the QR code multiple times as a kind of queue ticket, and we also received paper tickets for re-entry. I paid for the whole family together through KKday, and there were no problems. These days, many theme parks require each person to have their own smartphone and QR code, which can be inconvenient for toddlers and elementary school children, but Moominvalley Park didn't have that kind of inconvenience. (As of May 2026)
The JR Tokyo Wide Pass is great value for foreigners; it's convenient and affordable for trips to Kawaguchiko, Karuizawa, and Nikko.
