Little Cards from Japan (G1)

[Skullcruncher]

Hi, anyone know anything about these cards from Japan. (Trading cards or some sort of card game?)

There are some on ebay described as Menko cards.

Hey, I think these are "mini cards" incorrectly listed as menko cards on eBay. (The packet in your photo has ミニカード "mini card" printed in the front. I couldn't tell you what the back of the card says though, sorry!)
I'm guessing they're a type of trading card because this listing looks to have blind packs:

Menko cards have little dice and one of Rock Paper Scissors symbols on the back of them, they're also bit narrower.

This Japanese page had some really great reference, but it doesn't seem to be loading for me today:

Thanks so much, this is great information. I do actually have some G1 cards with a small rock/paper/scissors on the back of them too. :)
