Good to know you have good memories here!
And the food - it's really one of a kind! I'm getting fatter and fatter each day here.

Nobody can enter Japan right now?

Tourists are not allowed to enter right now. Actually, since covid started they aren't allowed to enter. Only special types of visa are allowed.
I think it will change soon. There are rumors going around that Japan will start accepting tourists again maybe next month or very soon.
