Shiko Jirushi (四光印, Four Lights mark) was one of Nintendo’s high-class brands of hanafuda decks.
The brand is named after the yaku of the same name. As such, it is not surprising that the brand was not used for kabufuda, mekurifuda, and other karuta decks.
It was the 5th highest-ranking brand in Nintendo’s hanafuda lineup, behind Masamune and followed by Ginsekai.

The brand was known to be used from the 1910’s to the 1930’s before it was discontinued. However, the brand has been listed on the end of the wrapper of most Nintendo decks (until 1967). The brand has become extremely rare. To this day, there is only one known existing deck that appeared on the internet.
