The kankara (Japanese: かんから) or kankara sanshin (literally "sanshin from a can") is a Japanese three-stringed folk plucked instrument, initially an improvised derivative of the Okinawan sanshin that was developed in the Ryukyu Islands during the Shōwa period.
Like the wooden-bodied gottan, the kankara is an inexpensive alternative to other, professional Japanese lutes – namely the sanshin and the similar, albeit larger shamisen. Unlike the gottan, however, the kankara was invented much later and served a much different purpose historically.
The kankara sanshin originates in the period following the World War II Battle of Okinawa. Okinawans, including men detained by the American military, made use of metal cans discarded by the Americans, and used them as the body for improvised sanshins.
Since World War II kankara have become popular as inexpensive alternatives to the sanshin or shamisen, and professional sanshin or shamisen makers have begun to craft them and include them in their stores, online and in catalogues. The kankara itself has also evolved to some degree, with certain makers creating more ornate instruments with hand-painted frontal designs and the decorative wrappings (手掛 tiigaa) that are a feature of the sanshin proper. DIY "build-your-own" kankara sanshin kits are also readily available.
