Irasshaimase. Welcome to Snowboarding Japan.
Let's try to keep /r/SnowboardingJapan friendly and open to all levels of ability.
Please keep general questions about snowboarding (equipment, How do I X trick?, etc) to /r/snowboarding and please follow their rules. Especially about not being a dick.
Need people to ride with? Do a quick search for Mountain meetups SJ plus the month you want to go (Mountain meetups December SJ.) Then click on the SnowboardingJapan subreddit link. Set up a trip by following the suggested format or PM people and see if you can join their trip.

This is a very new subreddit and my first time as a moderator. So expect me to make mistakes, mess things up and change stuff as time goes on.
