Japanese conch-shell trumpet of the type generally known as horagai.

Conch trumpets have a long history in Japan and are associated both with religious practice and with historical military signalling. The earlier Yamazakura listing described this example specifically as a samurai signal conch.

That identification is retained as the previous catalogue attribution, but no specific period, clan, campaign or individual provenance is claimed from the available catalogue information alone.

Origin: Japan.
Type: Conch-shell trumpet / horagai-style signal instrument.
Earlier catalogue identification: Samurai signal conch.
