Hanpen (半片) is a white, square, triangle or round surimi product (fish or meat paste) with a soft, mild taste. It is believed to have been invented during the Edo period in Japan by a chef, Hanpei (半平) of Suruga, and the dish is named after him. Another theory suggests that because it is triangle shaped and appears to have been cut in half from a square, it is a half (半, han) piece (片, pen). It can be eaten as an ingredient in oden or soup. It can also be fried or broiled.
