Kushiyaki (串焼き) is a formal term that encompasses both poultry and non-poultry items, skewered and grilled. At times, restaurants group them as kushimono (串物) and yakimono (焼き物).
Yakitori and kushiyaki
Both yakitori and kushiyaki are used interchangeably in Japanese society to refer to skewered meat collectively; however, when referring to a specific item, yakitori will not be used unless the primary meat is chicken. While using pork, grilled pork on skewers are cooked with the same sauce as yakitori, and that is why in some areas as Muroran, grilled pork on skewers are called "yakitori", instead of yakiton (やきとん, skewered and grilled pork).[1]
While kabayaki is also skewered and grilled over charcoal, it is rarely categorized as kushiyaki since they are not served on skewers.
Fish grilled whole on skewers with salt and served after pulling off the skewer including sea bream (tai) and sweetfish (ayu) is not called kushiyaki but shioyaki ("grilled with salt") at high-end restaurants. At food stalls or yatai, ayu is sold on skewers.
Variety
In order to facilitate even cooking, the ingredient is cut into small, roughly uniform shapes. Skewers or kushi are made with bamboo or Japanese cypress, and shape as well as length varies to use for the type of food: flat skewers are used for minced meat, for example.[2][3]

^In the mountainous area of Aichi, Gifu, Nagano, Shizuoka, Toyama and Yamanashi Prefectures, steamed and mashed rice basted on flat skewers and grilled with coat of sweet miso is called gohei mochi (ja:五平餅). When cooked rice is mashed and basted around kushi to form cylinders in Akita Prefecture, it is called "tampo" which is cut and cooked in kiritanpo.
