The Races of Rosuto-Shima

From publisher blurb:

Rather than the “standard” blend of fantasy races found in the Pathfinder Roleplaying Game, like dwarves, elves, and orcs, Steampunk Musha includes uncommon races inspired by Japanese, Chinese, and Korean mythology, as well as all new ones.

The sentient clockwork ronin, with their spirit-infused Gear
The volatile jinteki-oni, with the ability to unbind the beast within
The turtle-like kappa
The kijo, contemplative giants related to yetis
The snake-like sarpa, who straddle the divide between the mortal and undead realms
And many more

Presented in Steampunk Musha: The Races of Rosuto-Shima is everything you need to start playing these races at your table.
