For example, soy sauce used in Japanese sushi restaurants is usually neither “Koikuchi Shoyu (濃口醤油: dark soy sauce)” nor “Usukuchi Shoyu (薄口醤油: light-colored soy sauce)” but “Nikiri Shoyu (煮切り醤油: boiled-down soy sauce)” using Nikiri.

The most common, multi-purpose soy sauce, Koikuchi Shoyu generally has some acridity and is usually not used for sushi and sashimi.
