No, it’s not a game about the Cool Japan tourism campaign, unfortunately. Ishi-Sengokuden Sadame is Intergrow’s top-down action RPG thing with traditional Japanese creatures and stuff in it, and I think it looks interesting.
It’s got multiple playable characters, an armor and weapon upgrade system, and even a system that lets you import other players’ characters as partners. Not bad for an eShop game. It’ll be out in Japan this year.
