Answer by Michael Nolan for What were historically commonly used cooking oils in Japan?

Is there an oil that would be considered typical of the Japanese flavor profile?

Since you already quoted Salt, Fat, Acid, Heat, I would point to page 72 where the "World of Fat" map has an entry for Japan. It lists neutral oil, and sesame oil for Japan. Canola and soybean oil are both neutral oils, and would have been available in Japan historically.
