Worked out of the basics of the deck. I decided to use the mini card size from PrintNinja as the basis, which is 1.65″x2.5″ (still roughly half a Poker card). As of now, the deck will be 54 cards (32 tiles, 4 information cards, and 18 score tokens).
The main card, or tiles, didn’t change much with the size. I did re-work the score tokens a little, and may still change. Based on the size of the cards, I went with QR codes for the rules (and they’ve been tested). Thankfully, the Noto Goita Preservation Society has some nice rule sheets in both Japanese and English, plus a primer (Japanese only) that I could link to.

My hope is by combining the traditional Japanese character markings with their more western equivalents, it will make this deck easier for players to understand. I still need to decide on possible card materials, likely being plastic or PrintNinja’s 330gsm black core.
Next up – drafting a tuck box for the deck.
