The hut with accormodation is very few except for in the famous and popular mountains for trekkers, but hut is just open during season since May to October even in these mountaines. Hut usually provides drinks and souvenirs and only cash works there. Toilet is generally not there, even if available it is charged about $1-2. So papers with you sometimes help you.

It is recommended that you take your lunch box because the restaurant in hut is not available or even so which is instant food and very expensive.
Convenience store (Grocery store) is all over Japan.
There are a variety of food in which the breads agree with your taste, but if you are ready, try Japanese traditional but still most popular lunch, for example, Onigiri which is rice ball with some ingredients, such as tuna, salmon or Bento which is basically rice with some side dishes like meats, fish, eggs and vegitables.
Some Japanese trekkers take cooking goods shown in the picture and food materials, then they cook and enjoy their lunch on the summit.

As precaution for trekking in Japan, bears inhabit there. Bigger ones called Higuma inhabit Hokkaido, which is around 2-2.5m tall and smaller ones called Tsukinowaguma inhabit other 3 main islands, which is around 1-1.5m. Recently some accidents attacked by bears happened around mountain area, because bears try to look for their foods and approach to the residential areas due to poor harvest for their food and encounter the people. Some of them are of course fatal. Bears become more active in June and October. Trekking route is rarely to meet bear, but thinking about just in case, you first should avoid to accidentally encounter them. How? Make a noise, we usually do it by hanging the bell from backpack or listen to the radio.


This is the caution about bear. If you look at  or , be careful about bear and make big noise.
