Visual and microscopic analysis revealed details of the technique of manufacture. This is an <i>ikakeji</i> box which is decorated with a <i>katawaguruma</i> design made of <i>raden</i>. In addition, fine-lined wave patterns of <i>hira-makie</i> cover the entire <i>ikakeji</i> surface. The whole design is a very traditional one. There are many <i>tomoe</i> designs in <i>makie</i> on the underside of the lid which employ <i>hirameji</i>. Judging from the above techniques used, it is believed that this box was made in the 13th century. There is a box with a very similar design, which was made in the 12th century, at the Tokyo National Museum. However, the wave patterns are of <i>togidashi</i> technique and the design of the <i>katawaguruma</i> is also quite different. Therefore, these two boxes clearly show the differences in 12th- and 13th-century <i>makie</i> techniques. The <i>ikakeji</i> on this box may quite well be called <i>kinji</i>, for there is a brilliant shine. The <i>raden</i> is also made in strips approximately 1 mm wide. Each wheel of the <i>katawaguruma</i> is patternized. The longest <i>makie</i> lines of the wave pattern are 70 mm long, but they are also uniform. <i>Kinji</i>, <i>raden</i>, and the shape of the box are all typical of 13th-century techniques.
