Of course I know that there are really a lot of the channels in YouTube. I sometimes have enjoyed them and also have been surprised from then. because some foreigner has known to Japan more than me（I'm native Japanese）But I've learned a lot of things from them.
But at that time I also thought that what do they know more about Japanese cultures ?? I couldn't images then.
Please check my grammar.
And will you teach me clues and advices ?? I mean that why do you like japan ??
