Most Japanese don’t speak English fluently.
But in fact, most Japanese have studied English at school for more than six years.
However, English in school education is mainly learned for entrance exams, so most Japanese are not good at listening and speaking.
There is a hint to communicate with such Japanese in English.
- Speak slowly, separating words one by one.
If it is still difficult, it may be understood if you show the text. Japanese people are not good at cursive handwriting also, so the text may need to be written in block letters.
