For example in the nabe dish called sukiyaki it is possible to enjoy in one dish the synergistic effect of umami caused by the combination of inosinate from beef, glutamate from hakusai (Chinese cabbage) and the guanylate of the enoki. This ingredient can be used to increase the umami in a whole host of dishes.
