Hard to answer. I visited as a kid, and had a wonderful time.
Their toilets make me nervous, sad, & jealous. WWII (?)
They are very polite and formal. I hope they gave me a pass as a kid. If I were to go back, I'd be afraid I was not reciprocating their kindness in the appropriate manner. They would go 'too far' sometimes. To the point, I'd be afraid to suggest I liked something. My friend and I said we liked video games they took us to a friends house to play them. They went to get us a movie and went to great effort to get us one in English with Japanese subtitles.
