A rare historical term referring to a specific school of spear techniques (sojutsu). The cross-reference to 宝蔵院流 suggests this is a variant or related name.

Kamahozoin-ryu is a school of spear techniques known as a branch of Hozoin-ryu.
The more commonly referenced parent school of sojutsu; 鎌宝蔵院流 is a rare variant or branch.
The name combines 鎌 (kama, 'sickle'), 宝蔵院 (Hozoin, a temple name), and 流 (ryu, 'school/style'), suggesting a school of spear techniques associated with Hozoin temple and perhaps incorporating sickle techniques. The exact historical derivation is uncertain.
