Shidoin (EN: Instructor; JP: 指導員 or しどういん) is a Japanese honorific title for a martial arts instructor. The Nihon Kiin provides a similar title in go called the Nihon Kiin Igo Fukyu Shidoin (EN: Nihon Kiin Go Promotional Instructor; JP: 日本棋院囲碁普及指導員). As the Nihon Kiin's title implies, the role is for one who promotes the spread of go through instruction.
