I am Japanese and welcome you!

At first, most of Japanese can speak English a little, but we are shy enough to ignore you if you looks lost your way or in time of trouble.

Please start talking yourself; and then we can hear you.

I give you magic word in Japanese “Suimasen“ means excuse me, may I ask you?, I am sorry and more refer to context.

Anyway, i am sure you can enjoy your trip without learning Japanese.
