What yosegi-zukuri means
Yosegi-zukuri is a technique of Japanese wooden sculpture in which the head and main body of a statue are made from two or more separate blocks that are joined to form a single figure. Arms, legs and the spread of the knees are carved separately and fitted on. Because each block can be hollowed out before assembly, the sculptor can remove much of the interior, which keeps the weight down and limits the splitting that occurs as wood dries, and large statues become practical.
The opposite method is ichiboku-zukuri, in which the core of head and body is carved from one piece of timber. Between the two lies warihagi-zukuri: a figure is carved from a single block, split apart front and back or left and right, hollowed, and joined again. Yosegi-zukuri differs in that the blocks are separate from the start, though commentaries and scholars draw the line in slightly different places. The commentary on the statues inside the Konjikido of Chusonji records both split-and-rejoined and joined-block construction within the same group, and a single set can mix the two.
The method was refined in Japan during the mid-Heian period, and the seated Amida carved by Jocho for the Phoenix Hall of Byodoin in 1053 is regarded as its mature form. From then on it was the standard technique for large images, and the work of the Kei school in the Kamakura period also relies on it. Hinoki is the usual wood.
Reading the records and the statues
Records usually give the wood and the technique together. Some state only hinoki, joined-block construction in the material field; others describe the arrangement of the blocks in detail. The commentary on the seated Dainichi at Shuzenji in Shizuoka explains that the head and body are two blocks joined along the centre line, carefully hollowed, with the head cut free below the neck folds so that crystal eyes could be set from inside. The seated Amida at Engyoji is described as two blocks joined front and back along a line behind the ears, with further pieces added for the shoulder, the knees and the feet.
Three questions help in reading such a description: how many blocks form the head and body, where the joint line runs (down the centre or behind the ears), and whether the neck or the face has been cut free. Crystal eyes are fitted from behind, so a statue with crystal eyes will have its face split away and rejoined.
On the statue itself, a joint line sometimes shows where the lacquer gilding or paint has worn away. Where the surface is intact, the construction usually cannot be seen from outside, and conservation or survey reports are the reliable source.
