Not available in Japan

I have been browsing your products on Amazon.co.jp and a lot all of them are "Currently unavailable" and have been like that for a few weeks now.

They have not been banned or something like that in Japan right? If so I would like to know

Not banned. But we closed those list and will update later.

When's later?

Is it possible to buy one from another shop? Within Japan to avoid import tax etc.
