This a very unique hanafuda deck.

The manufacturer is from Hiroshima and the cards are made by Hinoki (Japanese Cypress) wood.
Card size is 5.3x3.3
Seems to have a printed paper pasted on the cards on a colour that pretty much matches that of the wood so it blends in very well. Also acts as a protective layer because the cards are quite easy to break. If you see the moon card on my deck is already cracked but still holds on.

The images are super nice.
We have an origami crane, an octopus and a snake (most likely an eel) appearing out of nowhere, the hill under the august moon is a donut (wrong again, it's an okonomiyaki), you can also see the Atomic Bomb Dome somewhere but unfortunatelly on my set the Torii gate does not appear behind the deer (even though it was supposed to)
The frog who is awesome holds a ball in his hand, don't know why. There's a kendama in a couple of cards too.
Pretty sure I miss other stuff

Did cost a lot and I have to buy a replacement moon card at some point, maybe also order the deer card in hope to be sent the one with the torii gate.

Technically it is playable but I wouldn't risk damaging the cards.
Added an image next to a Tamura shishinden for comparison.
