Abstract : Mango production in Japan is restricted to the southernmost district of the country. Cv. Irwin grafted on Formosa seedling is grown in plastic houses to be free from winter injury and anthracnose disease. Flower bud differentiation proceeds in autumn in response to cool weather on the terminal buds of the new shoots flushed after summer pruning. House heating starts in January with a night temperature regime over 23°C. Flowers open in February and fruits are harvested in June. This is the standard type of production. Another 2 methods are developing to expand the harvesting period to May and August. Flowering control is imperative to both systems. In all systems, fully red-coloured mature fruits with a Brix value of >15° are harvested. They are very expensive, but they satisfy urban consumers in place of the low quality imported mangoes (10?000 t/year). The production of greenhouse-cultivated Irwin mango in Japan is expected to reach 1000 t/year within several years.
