World Tropical Fruit Greenhouse, Togokusan Fruit Park (東谷山フルーツパーク 世界の熱帯果樹温室)

Togokusan Fruit Park opened in April 1980 at the south-western foot of Mount Tōgoku, which rises to 198.3 m and is the highest point in Nagoya, on the city's north-eastern edge. The city conceived it as a multi-purpose agricultural park: a place where residents could enjoy contact with nature, plant-watching and walks, and a means of supporting urban farming by teaching fruit-growing techniques.

The World Tropical Fruit Greenhouse was added to the open-air orchards in April 1985, five years after the park opened. A fruit pavilion, the Kudamono-kan, followed in May 1991. The park belongs to the City of Nagoya and is managed by the Nagoya City Green Spaces Foundation (Nagoya-shi Midori no Kyōkai). The sources consulted record no rebuilding of the greenhouse since 1985; they do, however, differ on the size of the collection, put at about 90 species on one page, around a hundred on another and, in detail, at 104 varieties.

The greenhouse is made up of two dome-shaped volumes, one large and one small. Their design takes as its model the zenpō-kōen-fun, the ancient burial mound whose name describes a square front joined to a round rear, many examples of which survive around Mount Tōgoku. One of them, the Shiratorizuka mound, lies a few hundred metres north-west of the park and belongs to the Shidami kofun group, a designated national historic site.

The single-storey building stands at the centre of the park, surrounded by orchards and visitor facilities. Entry requires a separate ticket from the park itself, so that the greenhouse works as an exhibition hall in its own right among the open-air plantings. None of the sources consulted gives the designer, the builder, or the floor area or height of the domes.

The greenhouse's official page lists 104 varieties and 282 tropical and subtropical fruit trees, chosen among the rare fruits of those regions. The species it names include mango, avocado, acerola, cherimoya, star fruit, passion fruit, papaya, several bananas, coconut palm and breadfruit, together with jackfruit (paramitsu) and its close relative the kopara-mitsu.

Around the greenhouse the open-air orchards grow some fifteen fruits familiar in Japan, among them peach, pear, apple and persimmon, and the park is known for its thousand or so double-flowered, deep-pink weeping cherries (yaebeni-shidare), which come into bloom together every spring.

The park lies in Moriyama ward, on the north-eastern edge of Nagoya. Buses, including a shuttle, stop at the Togokusan Fruit Park stop, and Kōzōji station, served by JR and the Aichi Loop Line, is about twenty-five minutes away on foot. Spring, when the weeping cherries flower, is the park's best-known season. A visit to the greenhouse combines with the fruit pavilion, the shop selling fresh fruit and local vegetables and, to the north-west, the burial mounds of the Shidami group.
