Rokuro seikei (wheel throwing)

Wheel throwing is the primary shaping technique in Japanese ceramics, in which centrifugal force allows a potter to pull clay into precise, symmetrical forms. Japanese potters distinguish between the electric wheel (denki rokuro) and the kick wheel (keri rokuro).

Wheel-Throwing (Rokuro Seikei) FAQ

Q1. What kind of tool is a potter's wheel (Rokuro), and are there different types available? A potter's wheel (Rokuro) is a tool featuring a rotating disk upon which clay is placed. It utilizes centrifugal force to quickly and uniformly shape round vessels such as bowls, plates, and jars. There are three main types, chosen based on the historical era, region, and the artist's personal style:

・Hand-turned wheel (Te-rokuro): A simple tool spun by hand, where the potter shapes the clay—often using hand-building techniques—while the wheel rotates on its own inertia.

・Kick wheel (Ke-rokuro): A traditional wheel spun by kicking a large flywheel at the base with the toes. This ancient method is still highly cherished today in historic wood-fired pottery regions like Bizen and Karatsu.

・Electric wheel (Dendo-rokuro): Powered by a motor to maintain a constant rotation speed. This is the most common type of wheel used in modern pottery today.

Q2. What was the greatest impact that the potter's wheel had on Japanese ceramic culture and history?

The greatest impact of the wheel was that it enabled the mass production (industrialization) of vessels, as well as the achievement of extreme thinness and uniform beauty.

Before the introduction of the wheel, hand-building—where clay is stacked by hand—was the standard method, which took a significant amount of time. However, the advent of the wheel capitalized on rotational force, allowing artisans to quickly craft hundreds of identically shaped vessels. This laid the foundation for the booming ceramic industries (Yogyo) all across Japan. Furthermore, the wheel made it possible to stretch the clay to its absolute limit, making it an indispensable tool for expressing Japan's refined aesthetic sense, as seen in the sophisticated porcelain of Arita ware and the elegant tea bowls prized in the Japanese tea ceremony.
