I was looking for a nice place in the mountain, which is not too far away from Tokyo. My solution was the little town Takayama in Gifu. It takes 5 hours by bus (Nohi Bus Service from Tokyo-Shinjuku). The view from the bus was great. I saw a beautiful winter landscape in a great mountainside with many lakes and dam.
I arrived in Takayama during lunchtime and walked straight to the old town of the city, to see many old nice streets full of handcraft shops, restaurants and small sake stores. I walked around and tried many sweets and drinks like amazake, which were very delicious. There was also the chance to try diffrent kinds of sake for just 200 Yen.
The day ended with walking through a long street with many temples, along a small mountain.
But I was very surprised. The city is very good for tourists. Every sign is written in Japanese/English and sometimes also in Chinese, Korean or French. At the tourist information you will find pamphlets in diffrent languages (English, Spanish, French, German..). Also mostly of the people in the tourist area can speak at least English and Chinese. Also you can do very easy daytrips by bus to Shirakawago and Toyama.
