Japan Pavilion, Venice Biennale (ヴェネチア・ビエンナーレ日本館)

The Venice Biennale opened in the Giardini in 1895, and from 1907, starting with Belgium, countries built pavilions of their own there. Japan put a pavilion design before the Biennale authorities in 1932, but the plan was dropped because of the war. Back on the international art scene after the Second World War, it took part officially for the first time in 1952; until 1956 it exhibited in a room rented inside the Central Pavilion.

The pavilion was completed in 1956 with a donation from Shojiro Ishibashi, founder of Bridgestone. It is the work of Takamasa Yoshizaka, who had studied under Le Corbusier. The 28th International Art Exhibition, from 19 June to 21 October 1956, brought six artists together there; Shiko Munakata won the grand prize in the printmaking section.

Run by the Japan Foundation since 1976, the building underwent several partial renovations over fifty years while it deteriorated and had to host exhibitions nobody had foreseen when it was built. The Ishibashi Foundation then funded a full-scale renovation, the first since construction, and commissioned Toyo Ito to carry it out ahead of the 14th International Architecture Exhibition. In 2025, with a further donation from the same foundation, Toyo Ito returned to the pavilion to make it more sustainable.

The pavilion pairs the international style with Japanese features. Its exhibition room has a floor area of 256 m². The walls are broken up by four projecting partitions, and an opening cut through the middle of the floor links the room to the piloti space below. From that space, stairs wind up around the garden to the entrance of the room above. Daylight comes in two ways: sunlight filters through a ceiling of glass blocks, and indirect light reaches the room through the ceiling louvres.

Both renovations are the work of Toyo Ito. The 2014 work sought to give the building back, as far as possible, Yoshizaka's intent and the look it had at completion; for Ito, it was above all the restoration of the garden and the return of natural light from the roof that brought that look back. The 2025 work replaced the polycarbonate fitted on the roof in 2014 with transparent solar glass, which covers about 30% of the pavilion's average annual electricity use. A 2,000-litre tank collects rainwater, among other things for watering the garden trees; insulation was improved without touching the existing architecture, with insulating paint on the outer walls and on the ceiling of the piloti space; and steps were added to the slope built in 2014.

The Japan Foundation organises the pavilion's exhibitions, both at the art Biennale, where it has presented leading Japanese artists since 1976, and at the architecture exhibition, in which Japan has officially taken part since 1991. For each one it prepares the show (shipping the works, installing them, producing the catalogue) and looks after press relations, management and the running of the pavilion while the event lasts. Over 200 artists and architects have shown work there.

The pavilion stands in the Biennale Giardini, in the Castello district, on Viale Giardini Pubblici. The pavilions of the Giardini can be visited while the Biennale exhibitions are open, art and architecture taking turns from one year to the next; entry is by ticket.
