It is still sold in Japan, go to store and pick it up.

It's available on the chinese ebay too...
Both in the new and old label (shorter expiry dates). The old label is significantly cheaper at around US$53 per box of 20. The new label is around US$81, same price as in Japan. But if you want to get it from there, you will need to find a middleman to ship it to you and they usually take 10% + shipping fees.
