Secrets of Japan
This sourcebook presents modern Japan as a setting for cosmic-horror investigations, combining ancient Shinto and Buddhist traditions with corporations, political intrigue, mass media, and experimental technology. It provides new investigator occupations, spells, monsters, organizations, and rules for Japanese characters, along with cultural background, religious details, a glossary, and a secret history of Japan. Three adventure scenarios and two short stories support play in this setting.
