Now that I have a one year visa for cultural activities (thank you, in-laws), the Japanese government has issued me an Alien Registration Card and enrolled me in the national health insurance program. Yipeee! For about $100 per year, I now have access to health care in Japan. My very first national health insurance. Thank you, Nihon!
It’s been a week of getting organized. I also got my bike re-assembled and registered, bought a bike helmet, and added a kick-stand. I am ready to roll.

Good for you. When I first came to Japan was the first time I had health care since I was a child. I have to admit that the methods over here are a little behind, but still not bad for almost free.
