The complexity of the Japanese language (日本語の複雑さ)

My Russian friend says that he doesn’t like English because the language is too simple and is hard to explain detailed feelings. But I wonder if he’s right because both he and I are English learners.

So I asked about his opinion to my Brazilian friend who speaks fluent Portuguese, English and Japanese. She answered that she doesn’t know a lot about the Russian language, but she thinks English is neither simple nor complex.

Then I asked her “So how about the Japanese language?”

She simply said “The Japanese language is crazy.”𿘂
