Is Japan a small country?

I’m genuinely curious—I often see posts on Reddit and elsewhere referring to Japan as a 'tiny island nation.'
Since they’re using the term 'island nation,' I assume they’re talking about land area. I wonder if the people saying this realize that Japan is actually larger than, let’s say, Germany?
Yet, I’ve never seen anyone call Germany a 'small country.' Are they calling Japan small without actually knowing its size?
