I am hoping to return to Japan for another trip sometime this year. One of my hopes for this trip is to do some hiking/nature day trips around Tokyo (such as Mt. Mitake and maybe Mt. Oyama or Mt. Tsukuba). On past trips, I have always traveled during May and June. For this trip, I am considering traveling during mid-March.

Would mountain hiking be reasonable during the mid-March season? And, would spots on/near the mountains be open (shops, restaurants, cable cars, etc.)? Since I've one travelled during the summer previously, I am concerned that such places may still be "closed for the season" in March. If so, I would make sure to travel during the summer instead.

I would appreciate any thoughts and advice the people may have - especially if you have personally gone to some of these mountain areas in March! Thank you!
