Where can I buy Eikoh figures?

Hello,

Where could I buy figures from the Miniature Planet series?
I am interested in 3 sets - two with dogs and one with cats. A total of 48 figures. Unfortunately, there is almost nothing on eBay.
The page below has some, but a few figures are not available there:

I would like to buy everything at once if possible.

Thank you in advance for your help and suggestions.
