The taishōgoto (大正琴?), or Nagoya harp, is a Japanese stringed musical instrument. The name derives from the Taishō period (1912–1926) when the instrument first appeared. It has also become naturalized in East Africa, often under the name Taishokoto.
The taishōgoto consists of a long, hollow box with strings running its length. Above the strings are a span of numbered typewriter-like keys, which when depressed fret or shorten the strings to raise their pitch. It is played lengthwise and strummed. There are also electrified versions of the instrument.
The taishōgoto bears a close resemblance to the bulbul tarang from India, and the akkordolia from Germany, all sharing the same principle of using keys to press down on strings to change their pitch. It also bears some resemblance to the Swedish nyckelharpa for the same reason although the action and the method of playing the strings is very different.
