Japan — chirashi zushi documented since Edo period as home and celebration sushi format; two regional traditions developed separately
Chirashi zushi (散らし寿司, scattered sushi) is Japan's most accessible sushi format — seasoned sushi rice in a bowl or lacquered box, topped with a colorful arrangement of seafood and vegetable garnishes. Unlike nigiri (individually crafted), chirashi can be made in large quantities for festivals and celebrations. Two distinct regional traditions: Edomae chirashi (Tokyo) — raw fish on white vinegar rice, individual arrangement echoing nigiri toppings; Kansai chirashi (barazushi) — cooked, pickled, and preserved toppings mixed into rice (no raw fish), historically for non-coastal areas. Chirashi is the standard home celebration sushi for Hinamatsuri (Girls' Day) and spring gatherings.

{"Rice preparation: same sushi rice as nigiri — vinegar/salt/sugar seasoned, body temperature","Edomae style: fresh raw fish sliced thick, arranged over rice — similar toppings to nigiri menu","Kansai barazushi: cooked ingredients (renkon, kampyo, shiitake, carrots) mixed into rice","Color composition: five colors guideline — red (ikura, shrimp), white (hirame), yellow (tamago), black (nori), green (shiso)","Height layering: standard base rice, second layer of smaller ingredients, final layer of premium items","Presentation: served in lacquered ohitsu (rice tub) or individual lacquered bowl — visual luxury"}
{"Hinamatsuri chirashi: ikura, shrimp, and scrambled egg for spring color — symbolic pink and gold","Tamago sheet: rolled thick tamago sliced thin and scattered — adds sweetness to savory composition","Kinshi tamago: egg beaten with sugar, cooked very thin, julienned fine — golden confetti garnish","Wooden ohitsu serving: wood absorbs slight moisture from rice, improves texture over ceramic","Topping order: proteins first, then garnish (shiso, nori strips, negi), then microgreens last"}
{"Cold rice — chirashi rice must be room/body temperature; refrigerator-cold rice ruins the experience","Arranging too densely — visibility of each topping and color contrast require spacing","Kansai style: under-seasoning the mixed ingredients — each component should be clearly seasoned before mixing"}
