Yamabiko Corporation

The Kioritz Corporation (Japanese: 共立) (Kyōritsu) was a global manufacturer of forestry and agricultural machinery, as well as outdoor power equipment. The company was founded on 8 September 1947, by the Asamoto brothers, primarily to manufacture agricultural machinery. Until 1971, the company operated under the name, Kyoritsu Noki Company. In 1971, the Kyoritsu Noki Company changed its name to the Kioritz Corporation and launched the CS-302, its first 'professional' saw and the first to bear its distinctive orange casing.[3] It began trading under the Echo brand name in 1978.[4]

The first Kyoritsu Noki brushcutter was introduced in 1960 and three years later, the company launched its first chainsaw, the Echo CS-80, and the first Kyoritsu Noki tool to bear the "Echo" brand name. In 1970, Kyoritsu claimed to have 'revolutionized' outdoor cleaning with the PB-9, a backpack power blower.
