What's the best time to climb Mount Fuji?

Hi there, I’m planning a trip to Japan in 2025 and would love to climb Mount Fuji. When is the climbing season, since it seems to be closed in winter? As a mountaineering hiker, I’m interested in the least crowded route. Thanks for any recent tips, and happy New Year to everyone! Aichatou

Hello, The opening dates are from late June to early September. Outside of these dates, the mountain huts and temples are closed, but it’s not forbidden to go there. However, mountain experience is required outside of these dates. We did it the week after the closure—we didn’t meet anyone, but you need to be well-equipped for the cold wind and have good physical condition (you often reach nearly 4,000m without acclimatization). There are accidents every year. Happy hiking!
