The Japanese dashi is easier and takes less time to make than with the western broth.
Unfortunately though, when various chemical seasoning became available in stores, many Japanese have abandoned their practice of making dashi from dried bonito and seaweed, because they found it to be too troublesome. It really is a pity.
