The "sun" in the name is a Japanese form of measurement. Each "sun" is approximately 3 centimetres in box length. The last part of the title is the name of the pattern displayed on the box. The wood koyosegi pattern that is laid on the top and bottom panels may be different from the picture because parquet (Wood mosaic) design is created in a continuous pattern and then affixed to the puzzle box.
