The trip started from Narita Airport and went directly to Shimoda in Shizuoka Prefecture, and then to Kamakura. The JR Tokyo Wide Pass can save a lot of transportation costs and can be used for three consecutive days, which is very convenient.
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)
During my recent trip to Japan, I used KDDI's eSIM, and the 5G network speed was extremely stable and smooth. The setup process was simple and quick—just scan and use. Whether navigating in the city or taking photos in the mountains, the network connection never dropped. With 12GB of storage, it's the perfect high-value choice for a family trip!
