Hi,
I have collected a few essential Japan travel tips over the past 10 years or
so. Not intended as a tourist travel guide, but just some things I normally do
that people might find helpful:

I might be able to extend this a bit - let me know if you have feedback or
questions.
If someone wants to adopt some of this information for the meeting Wiki, that
would be fine with me.
I hope you will have a great time in Yokohama!
Best regards,
Dirk
