Manaita

Manaita (俎板 / 真魚板) refers to the traditional Japanese cutting board. The older spelling 真魚板 (literally “board for true fish”) points to its original use as a surface for breaking down fish: in early Japan, all side dishes served with rice were called na (菜); fish and meat were distinguished as mana (真魚) through the prefix ma (真, true). The spelling in common use today, 俎板, is a Sino-Japanese overlay. The character 俎 combines the elements for flesh (月) and sacrificial stand (且), alluding to its ritual function: the manaita was originally the table on which food for offerings to the gods was prepared.^1, 2

The word survives in kitchen terminology: itamae (板前, “in front of the board”), itaba (板場, “place of the board”), hanaita (花板, “flower board”), and wakiita (脇板, “side board”) all derive from ita (板), the board that was originally the manaita.

The manaita was not a flat board but a heavy table with legs, known at court as kiritsukue (切机, cutting table). Work was done seated, and to make it easier to cut through hard bones and sinews, the surface of many early manaita was convex, shaped like a kamaboko. The cook guided the blade along the crest, concentrating force on a narrow ridge. The Engishiki (延喜式, 927) records sixteen manaita for the imperial kitchen, separated by use—for fish, vegetables, sweets, and side dishes—with a length of about 91 cm (36 in) and a height of more than 24 cm (9.4 in).²

The manaita also stood at the center of hōchōshiki (庖丁式), the courtly cutting ceremony of the Heian period. Different knife schools defined their own dimensions: the manaita of the Shijō school measured about 83 cm (33 in), while that of the Ōkusa school exceeded 1 m (3.3 ft).²

Only in the Edo period did the manaita lose its legs. Street vendors placed flat boards across tubs, and this compact form became standard in townspeople’s kitchens, remaining so into the 20th century. Since the 1960s, plastic boards have dominated the household market.

Professional manaita are made of wood. The four classic woods are ichō (イチョウ, ginkgo), hinoki (ヒノキ, Japanese cypress), hō (ホオ, Japanese magnolia), and yanagi (ヤナギ, willow). Ginkgo is considered the most versatile material: the wood is soft enough to protect the blade, even-grained, dimensionally stable, and naturally resistant to odors. Japanese cypress offers the strongest antibacterial effect and is often used in sushiya. A wooden manaita can remain in use for decades: when the surface is worn down, it is planed and the board continues to be used.
