Tenkasu

Tenkasu (天かす) are crunchy bits of deep fried flour-batter used in Japanese cuisine, specifically in dishes such as soba, udon, takoyaki and okonomiyaki. Hot plain soba and udon with added tenkasu are called tanuki-soba and tanuki-udon (haikara-soba and haikara-udon in Kansai region).

They are also called agedama (揚げ玉). According to the NHK Broadcasting Culture Research Institute, 68% Japanese called them tenkasu and 29% agedama in 2003. Tenkasu is more common in western Japan and agedama is more common in eastern Japan.
