The wood type is unknown, but it's a sanshin with beautiful wood grain. The neck alone weighs 477g. It has a comfortable thickness. The milk bag (where the strings attach) has a firm rise, making it easy to play. It has reinforced skin, so it's sturdy and produces a pleasant, round sound. Please check the condition in the photos. Accessories include a standard uma (bridge), a mute uma, and a stand. This is a used item, so please understand it's sold as-is (no returns, no refunds, no exchanges).
