Yahajiki

Yahajiki was a large ballista onboard of a ship that launched bolts across the waters. It was developed after members of the Tsuruchi sailing on the Mantis realized the kobune relied only on occasional Moshi Shugenja to affect their opponents at range. Yahajiki were perfect for the larger of the Mantis Clan fleet's vessels, the sengokobune. The device was quickly copied by the Crab for their koutetsukan vessels.
