Tohoku Japan Shared Ride Day Trip | Ginzan Onsen, Zao Snow Monsters (Juhyo), Miyagi Zao Fox Village, Okama Crater | Departing from Sendai
2026/10/17
Reaching the foot of Mount Zao was truly a challenging journey, and we are very grateful to our guide, Xiao Li, for driving so smoothly that everyone made it to the attraction safely. Although Ginzan Onsen is small, it has a wonderful atmosphere, and winter is the perfect time to enjoy a relaxing visit.
