Authentic low-poly Japanese corner watchtower (sumi yagura) - game-ready and optimized for real-time rendering in Unity, Unreal Engine, and other game engines.

2-tier compact watchtower in the Edo-period white-plaster style of Himeji and Matsumoto castles. Built atop a battered ishigaki stone base, with white plaster walls, vertical lattice windows (renji-mado), black tile hip-and-gable (irimoya) roofs, golden shachihoko on the ridge, and defensive loopholes (rectangular for arrows and cross-shaped for firearms).

Designed to flank a castle compound - perfect at the corner of an ishigaki wall. Part of the Japanese Castle Set (pairs with SM_Tenshu, SM_IshigakiHei, SM_Yakuimon).

Features:

• Battered stone base (ishigaki) with fan-curve taper
• 2 stacked tiers (smaller than the main keep)
