Kirk here with an inquiry that was directed to the page:

— start quote — Hello, I will be leaving Kumamoto/Japan at the end of this month. I had intended to sell my car but cannot find the registered inkan. I have my shaken documents and such and the little green book they gave with the inkan. it seems to be able to sell or get rid of my car I need that. I don’t know what to do in the case of having lost it. If you know anything, can you please help? πŸ˜“ — end quote —

Just after I posted this I got the following update:

— start — I’m sorry I didn’t give an update, I was able to resolve it at city hall. They were able to register a new inkan. — end —

So, this issue has been resolved. I can say from my own experience, though, that if you register and inkan, it’s important to keep track of it and the registration documents (green plastic, as I recall) that come with it.

P.S. The generic inkan image I added came from the following page:
