Ichi = One
Ju = Soup
Issai = One dish
Ichiju Issai is came from Ichihu Sansai (Three dishes) and which style makes Washoku ( Japanese cuisine ) blanced foods. However recently almost all of Japanese are really busy and it is hard to make dinner with three dishes after coming back from working therefore one of famous and popular Japanese Chef, Yoshiharu Doi , suggested us to make Miso soup which can be one dish and rice ( any carbohydrate is fine ) instead.
I cannot explain everything of Ichijiru Issai but I am sure that homemade Ichijiru Issai meal saves Japanese and make us satisfied from our hearts. One dish which contains love of a person who made the dish is much more valuable and has a power to make people happy and healthy.
