Japan for first timers?

Hi all! I’ve posted before about being up in the air about going to Japan for my honeymoon. But I think we have decided to go for it.

However, I am a little nervous it will be way too much for us.

My fiancé has never been out of the country before and I’ve only been to Greece.

We chose Japan because we know it’s like nothing we have ever experienced before and we wanted that difference.

But — will it be too much? Is the language barrier especially bad?

I am worried about getting around without being able to read the signs. Or knowing what to do or where to go.

Any help or insight is a
