Notes:
And for something a bit lighter and a lot more fun ..
These links take you to a You-Tube channel that features dozens of videos by fun, sometimes funny young Japanese who want to share offbeat aspects of their culture with you.
Weird vending machines, basic etiquette, and more.
Don't miss the vids on Ameyoko (you'll be there, you'll LOVE it, that's a promise) and other places in Tokyo.
