How to enjoy your stay in Japan?
1.Communication in English
There are few inconveniences as there are English signs and menus at stations, trains, traffic signs, and major restaurants.
However, if you're worried, it's a good idea to get a brief conversation book and be ready.
2.Travel Without Car
Specifically in urban areas, travel by train or subway is smooth. It is also common to travel by train to tourist destinations and rural areas. There is a good bus service in many areas as well.
If you plan to rent a car, make sure you have a valid driver's license for driving in Japan.
