This mansion's construction started during the Meiji Era and underwent upgrades and expansion through the Taisho and early Showa Periods. The house is a prime example of modern Japanese architecture.
The land area spans 7,568 square meters, while the residence in itself has a floor area of 1,019 square meters. This chic mansion, with its elaborate garden, was where the famous poet Byakuren Yanagihara spent her days. It is owned by the "King of Coal Mining," Den'emon Ito, and the only building that can speak of the cultural significance of coal mining in Iizuka City, where only a few existing establishments that tell the heritage of coal remain.
The property's high walls face the old Nagasaki Highway, and its gate (called Nagayamon) was relocated from a villa that caught fire in 1927 in Tenjin, Fukuoka (a property called the Copper Palace). This, together with the former office and store of Den'emon Ito, is eye-catching. The mansion is made up of five buildings - the Minami-mune (property facade), Kita-mune (facing the garden), Kadonoma Nakanoma-mune (which connects the two aforementioned buildings), the foyer and dining hall building, and the Tsunagi-mune - and three storehouses. A house of modern Japanese architecture, this residence has a vast stroll garden that surrounds a pond.
This structure displays the beauty of harmonious compromise between Western and Eastern architecture. From the sitting room's art-noveau mantelpiece, and diamond-shaped stained glass windows made in England; to the long corridor lined with tatami mats in a single line - different artistic techniques were applied during the construction of this mansion, which made it an architectural structure that was ahead of its time. The attention to detail and the exquisite decor can be seen throughout the house.
It is also a house that speaks of the history of the 10-year marriage between Den'emon and his wife, Akiko (Byakuren) Yanagihara. The history of coal mining in Chikuho, and the heritage of the life of Den'emon and the people around him, can all be seen in this structure, so please explore it to your heart's content.
