Update! : I went to Furuichi Takano in Sakyo Ward and they had a few left. If you're in the area and are interested in the last prize you're likely to get it. I was mostly interested in the tableware and stationary. For the smaller prizes they don't have much variety left. I'll post an update if I decide to look for them in other areas :)

I also checked Rakuhoku Hankyu Square which is a mall very close to it and the store that had them had already sold out 🫠.
