旧磯野家住宅

The Isono Residence is a traditional mansion with copper plates covering its roof and exterior walls, earning the nickname 'Copper Palace' from visitors. The structure combines a three-story reception wing with single-story study and kitchen areas.

Built between 1909 and 1912 for businessman Kei Isono, the residence reflects architectural evolution during Japan's shift from the Meiji to Taisho period. This transition era shaped its style with modern influences on traditional techniques.

The residence displays traditional Japanese carpentry through its intricate ceiling patterns and sliding door designs, reflecting daily craftsmanship practices of its era.

The residence is located three minutes on foot from Myogadai Station on Tokyo Metro's Marunouchi Line and opens for viewing during specific periods throughout the year. Visitors should check ahead for opening dates to avoid disappointment.

The copper roof is so striking that it earned the nickname 'Copper Palace' and stood out distinctly from other houses of its time. This visible copper covering made the property a recognizable landmark in the neighborhood.
