Seven fish, each one unique, are realistically portrayed in high relief against a ground descriptively named fish-roe (namako). The gold fish is a sea bream (tai), the long one a half-beak (sayori). The sea bream, prized for its red flesh, is often served on celebratory occasions. A halibut or flounder (karei) is among the fish on the opposite side. Seven is a lucky number in Japan. On the seventh day of the new year, rice porridge seasoned with seven herbs is served to protect against evil and bring good luck and longevity. The Star Festival, celebrated on the seventh day of the seventh month, is the most popular day to be married. The samurai code (bushido) contains seven basic principles generally understood to be righteousness, courage, benevolence, politeness, honesty, honor, and loyalty.
