Can I make a domestic call from a hotel in Japan?

It will be expensive to make an international call from the hotel.

If you are in Tokyo, you can dial 0345900 120-86- area code and telephone number with the hotel phone. Indoor calls are only charged. 10 yen can be said to be three minutes. There will be an advertisement in Japanese after you broadcast 0345900 120. Don't listen to it. Just dial the domestic number directly.

Be careful not to add 0 before the area code.
