This is supposedly the previous generation Munetaka's probably "Jō-no-Yae" (or "Tokujō-no-Yae"). The length is 98cm and the weight is 30g. Purchased from a kyugu (archery equipment) store, it's in beautiful condition, having only been used a few times for practice. It's a very high-quality yae (arrow shaft), well-dried and firm. Even if the fletching gets damaged through use, you should be able to replace the feathers and continue using it.
