After a lot of digging I found some really hard to find fuchikos. First, we have a museaum figure. The Otter and Fuchiko is only sold at as a blind-box at a zoo in Osaka. Not only do you have to travel to the zoo, pay for admission, you also have to be super lucky to get the fuchiko.
Next up is the changing clothes fuchiko. This popped up on the store before and was available only at a special shop here in Tokyo for a limited time. It's getting harder and harder to find these, let alone a full set. Only a few more sets are out there in the wild and are more are dissapearing each day.
Finally, not quite a fuchiko but still an edge-of-the-cup set. Kagome, a brand of juice in Japan, had a competition. 1,000 winners recived a large box with 10 figures from Morning Masume, a Japanese idold group. Like the changing clothes, these are getting really hard to find. I don't know how much longer I can keep them on the shop.
As always, if there is something you're looking for I can find it! Just send me a request.
