日语关系不好怎么说英语

如果你想表达日语能力不佳，可以使用以下表达：

My Japanese is not very good.
I'm not very proficient in Japanese.
I'm not very fluent in Japanese.
My Japanese skills are not very strong.

你也可以使用其他表达来谦虚地描述自己的日语能力，比如：

My Japanese is a bit rusty.
I'm a bit out of practice with Japanese.
I'm not as good at Japanese as I'd like to be.

当然，如果你想更加明确地表达自己的日语能力，你可以使用一些程度副词，比如“slightly”（稍微），“fairly”（相当），“quite”（相当）等。例如：

My Japanese is slightly better than basic.
My Japanese is fairly conversational.
I'm quite comfortable speaking Japanese, but my reading and writing skills are weaker.

希望这些表达对你有帮助。
