Tenryu Gakki


Before the wars, Tenryu Gakki was established by some of Yamaha engineers
after merger with Fuji Gakki. The origin of the Tenryu Gakki was a manufacturer
for airplane parts, but Mr. Hirano innovated on the company and gathered
Yamaha engineers. After the change to the Tenryu Gakki manufacturer, they started to
design and create Eterna. Thus, the model of E7 from Eterna was equivalent with E7
by Yamaha. Owing to the high-level technics, Yamaha supported Tenryu Gakki in capital,
and Tenryu had manufactured various pianos and parts as OEM product.
In 1953, the Tenryu Gakki was merged into Yamaha.
