They generally don’t, but there are many Japanese proxy shipping services who buy the items for you for a small fee and then ship from their warehouses to you. I mainly use Buyee, but there are many out there which all do different things slightly better/worse. They can also combine multiple orders into one when they ship to you. You can search Yahoo Auctions & Mercari pretty effectively by copy+pasting the Japanese set and card names from Bulbapedia, as well as using this thread and google translate. The cards you’ve picked up so far look great btw.
