I like the website. It's very cute and the style is great.
It's just that it's, as Mike Cash has said, really long.
I did a little skimming of it and found many information I could do without.
Maybe you could make a separate, more informative, shorter blog post?
Like, visa processing, some tips on travel, how long it took, etc.?
I guess I am a very boring person, but I love to read about those things haha.
And by the way, I hope you have a fun time in Japan!
