Seizansō

Seizansō is a residence in Hitachiota, Japan, recognized as a place of scenic beauty and historic significance. The single-story building carries a thatched roof over plain walls and houses a study room with three tatami mats and a circular window.

Tokugawa Mitsukuni, the second lord of Mito Domain, lived at the property from 1691 to 1700 while overseeing the compilation of the Great History of Japan. The building visible today dates from 1819 and follows the original design without ornament.

The entrance path leads through tall Kumano cedar trees that Mitsukuni brought from Kishu province, forming a natural canopy above visitors. These trees still stand where they were planted centuries ago, shaping the approach to the building.

The property opens daily from 9 to 16, and admission includes both the building and the gardens. Visitors should allow enough time to walk through the full grounds, exploring the rooms and the outdoor areas.

The three-tatami study room with its circular window shows the former resident's preference for a simple environment in which to focus on his work. The clear design of the room reflects his restrained way of life and his dedication to writing.
