In major cities such as Tokyo, Kyoto, and Osaka, speaking Japanese is not essential; however, learning a few basic phrases—such as “hello,” “thank you,” and “excuse me”—is highly recommended. These small gestures of courtesy are appreciated and can greatly enhance your experience. In rural areas, English and other foreign languages are far less common, making even a modest knowledge of Japanese particularly useful.
Public transportation throughout Japan is designed with international visitors in mind. Announcements are generally provided in both Japanese and English, and clear pictograms and universal symbols are widely used, ensuring that travelers can navigate with confidence.
