Hot, plain soba and udon with added tenkasu are called tanuki-soba and tanuki-udon, respectively (haikara-soba and haikara-udon in the Kansai region).
They are also called {{Nihongo|agedama|揚げ玉||literally "fried ball"}}. According to the NHK Broadcasting Culture Research Institute, 68% of Japanese people called them tenkasu and 29% agedama in 2003. Tenkasu is more common in western Japan and agedama in the east.
