Traveling in Japan can be challenging due to language barriers, as English speakers are scarce, even in major cities. The Google Translate app, particularly its voice input feature, proved essential for communication, allowing users to translate spoken Japanese instantly. Google Lens also facilitated understanding written Japanese by translating text captured through the camera. While apps are helpful, learning basic Japanese phrases is recommended for situations when technology fails. Engaging with locals in Japanese is encouraged, as it enhances the travel experience.
