The bow was carved out from a single wood (Cephalotaxaceae) and we can often see the bow that was bound with wood barks or hemp and fixed with lacquer for itsreinforcement (the bow of this period is referred to in archeology as 'Marukiyumi' (bow made from a small sapling or tree limb (often catalpa wood) and had a centered grip)).
弓は木（イヌガヤ科）から削り出した単一素材で、補強の為に樹皮や麻を巻き締め漆で固めた弓も屢々見られる（考古学的にはこの時代の弓も「丸木弓」と呼称している）。
