Itsuo Museum of Art (former Main Building)

A Railway Founder's House Where Art and Daily Life Shared a Roof

In January 1937, at the foot of Mount Satsuki in the Osaka suburb of Ikeda, the businessman Kobayashi Ichizō completed a home and gave it a name that read like a manifesto: Gazoku-sansō (雅俗山荘), the "villa of the refined and the everyday." The two characters he chose, ga for cultivated art and zoku for ordinary life, declared his intention to let beauty and daily living occupy the same rooms rather than keep them apart.

The building that carries the official name Itsuō Museum of Art, former Main Building, is that house. It is a two-storey reinforced-concrete structure with a floor area of 438 square metres, built by the Takenaka Corporation to a design by Kobayashi Risuke of the firm's design department. It sits at the northeast corner of the grounds, its entrance opening toward the west. Ichizō (1873–1957), founder of the Hankyu railway network and of the Takarazuka Revue, used the pen name Itsuō (逸翁) as a devoted follower of the tea ceremony, and that name later passed to the museum built around his collection.

The house reads at a glance as a Western villa, yet the roof is laid with silver-grey tiles in the Spanish pantile shape, a Japanese touch on a foreign silhouette. On the upper walls, exposed posts, beams and diagonal braces form a half-timbered pattern, while the entrance is faced in yellow Tatsuyama stone (ryūzan-seki), a limestone quarried in nearby Hyōgo. Along the upper storey runs a row of quatrefoil ornaments, four-lobed motifs that lend the gable a decorative rhythm.

Why the House Became a Registered Cultural Property

Ichizō died in 1957, and that same year his residence opened to the public as the Itsuō Museum of Art, displaying the roughly 5,500 objects he had gathered over a lifetime, among them fifteen works designated Important Cultural Properties. For half a century visitors came to the villa itself to see paintings by Yosa Buson and the tea utensils of a serious collector.

In 2009 the museum moved to a purpose-built gallery beside the Ikeda Bunko library, and the old villa reopened in 2010 as the Kobayashi Ichizō Memorial Hall, its interior restored to the state in which its owner had lived. In August 2009 the main building, together with its gate, its wall and two tea houses, was entered in the national register of Tangible Cultural Properties. The main building bears registration number 27-0530, recorded on 7 August 2009, and was listed under the criterion of contributing to the historic character of the national landscape.

What the registration recognises is not a single celebrated feature but the coherence of the whole. The design fuses Japanese and Western elements without letting either dominate, and it captures the taste of a Shōwa-era industrialist who treated his own dwelling as a work of applied art. A second-floor storage vault, built into the concrete structure, shows that the collection and the house were conceived together from the start.

What to Look For on a Visit

Approach from the west and the entrance greets you first: the warm yellow of the Tatsuyama stone against the concrete, and above it the quatrefoil band. Step back and the roofline gives the game away, its Spanish-shaped tiles glinting in a colour closer to Japanese lead-grey than to Mediterranean terracotta. The half-timbering on the upper walls rewards a slow look, since the pattern of braces was drawn as much for effect as for structure.

Inside, the memorial hall keeps the reception rooms and living quarters as they were, so the visit is less a gallery tour than a walk through a private life. The ground floor now holds a restaurant, also named Gazoku Sansō, where French cuisine is served in the rooms Ichizō once used. Beyond the house lie the garden and the two tea houses he commissioned, and the neighbouring museum still pours tea in a recreation of his most inventive tea room. The site rewards unhurried attention: this was a house meant to be lived in, and it still feels that way.
