Dam cards for the "Gunma Dam Karuta" game. I've completed 44 dam cards through trading with others. I understand that these are not meant to be exchanged for money. I'm releasing these to collect unvisited dam cards and different versions. I won't sell them individually as that would defeat the purpose. I'm also open to trading for an equal number of surplus cards, so please contact me in the comments if you're interested. https://www.pref.gunma.jp/page/11257.html
