Musashi Province

Musashi Province (武蔵国 Musashi no kuni^?) was a province of Japan, which today comprises Tokyo Prefecture, most of Saitama Prefecture and part of Kanagawa Prefecture.^[1]

It was sometimes called Bushū (武州^?).

The province encompassed Kawasaki and Yokohama.

Musashi bordered on Kai, Kōzuke, Sagami, Shimōsa, and Shimotsuke Provinces.

Musashi was the largest province in the Kantō region.

Musashi had its ancient capital in modern Fuchu, Tokyo and its provincial temple in what is now Kokubunji, Tokyo. By the Sengoku period, the main city was Edo, which became the dominant city of eastern Japan. Edo Castle was the headquarters of Tokugawa Ieyasu before the Battle of Sekigahara and became the dominant city of Japan during the Edo period, being renamed Tokyo during the Meiji Restoration.

The name Musashi, recorded in early records as 牟射志 munzasi, appears to be of Ainu origin. It has no meaning in Japanese, but mún-sa-hi (grass-plain-POSS)^[2] means "grass plain" in Ainu, and Musashi sits in the middle of the Kanto plain.^[3]
