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.
