Once, in the 1960s, we had a strange elongated instrument come through our music store -- the Old Town Folklore Center in Chicago. It had keys/buttons to push that stopped the strings at various adjustable/changeable positions on the strings. Called a NAGOYA HARP, I think it probably was made in Japan. It sounded quite oriental--as does the instrument here -- to my ears anyhow.

Nagoya, I think, is a city in Japan.
