This is an unsigned (mumei) Okago Yari, a rare type of spear designed to fit inside a basket. It features a midare (irregular) hamon and is free of rust and chips. The yari comes with a koshirae measuring 82cm in total length, adorned with a family crest of nine bamboo leaves within a circle, indicating a high-ranking former owner. Due to its short nagasa of 8.6cm, it does not require a registration certificate.

We could not find an authenticity certificate on the seller’s listing. Japanese swords and fittings are normally papered by the NBTHK (or the NTHK). Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
