South of the main house, this 1889 reception hall opens onto a 32-mat room and a long veranda facing the strolling garden, famous for its autumn colour.

In the northeast of the grounds, this late-Edo farmhouse moved from Kashiwazaki, with a thatched three-room plan and earthen floors, is the oldest here.

The residential core of the former Ito estate, completed in 1887 and now the heart of the Northern Culture Museum, with a 30-metre Aizu cedar beam overhead.

At the quiet western rear of the estate, this sukiya-influenced parlor of 1889 uses fine timber and soft sand-plaster walls, a gentler note than the main house.
