Kabocha
A sweet winter squash of Japanese origin, versatile in cooking.
Kabocha is a type of winter squash, a Japanese variety of the species Cucurbita maxima, also known as kabocha squash or Japanese pumpkin in North America. It is hard on the outside with knobbly skin, often dark green, red-orange, or gray, and has an intense yellow-orange interior.

Lore & Background
Portuguese sailors introduced kabocha to Japan in 1541, bringing it from Cambodia. The Portuguese name Camboja abóbora was shortened by the Japanese to kabocha; alternatively, the Portuguese word cabaça for gourd may be the origin. In Japan, kabocha can refer to this squash, the Western pumpkin, or other squashes. In Australia, 'Japanese pumpkin' is a synonym of Kent pumpkin, a variety of C. moschata. Many kabocha in the market are kuri kabocha, a type created from seiyo kabocha (buttercup squash). Varieties include Ajihei, Ebisu, Emiguri, Marron d'Or, and Miyako.
Reader's Guide
Kabocha is widely cultivated in Japan, South Korea, Thailand, parts of the United States, Mexico, Tasmania, Tonga, New Zealand, Chile, Jamaica, and South Africa, and is adapted to climates with a growing season of 100 days or more. Most kabocha grown in California, Colorado, Tonga, and New Zealand is exported to Japan. In Japan, it is used in vegetable tempura, soup, croquettes, and desserts such as pies, pudding, and ice cream. In Korea, danhobak is used for hobak-juk (pumpkin porridge). In Thailand, fak thong appears in traditional desserts and main courses; in Jamaica, it is used in chicken foot soup. The squash is rich in beta carotene, iron, vitamin C, and potassium. Ripening is a deliberate process: after harvest, kabocha is kept warm for 13 days to convert starch to sugar, then stored cool for about a month to increase carbohydrate content, reaching peak ripeness 1.5–3 months after harvest. All squashes were domesticated in Mesoamerica, with evidence suggesting domestication 8,000 to 10,000 years ago.
