The most important was to find ATM accepting our credit cards. I didn't expect it will be that difficult, but it turned out that most ATMs accept only Japanese Visa and MasterCard cards and not ours. Fortunately post office has ATMs accepting foreign cards, so we finally have enough cache to survive next week ;-).

The next step was to buy something we can start to learn Japanese a bit. It would be great to be able to read at least some signs and menu in restaurant. We bought few books, but later in restaurant it turned out to be almost useless. Fortunately the cook can a bit English, so we managed to order something we wanted. But this is the largest problem here - our poor Japanese knowledge as there was not time to prepare for this back at home...
