The "Piles on the Water" series, an irregular series that ran from 2001 to 2008, was suspended for a few years and then re-titled "Piles" in 2011. The policy of not being concerned with the specific colors "typical of water surfaces" as long as the fluidity and quietness can be expressed is the same as in the previous series, but in this series, the artist has challenged himself to construct "landscapes of various piles" by adding motifs other than piles and arranging them in relation to the piles. This is the 18th work in the series. It is characterized by a highly abstract and minimalist screen style within the series. Although the work has a subdued taste with metallic colors as the main color, the center of the screen and the interconnected piles are based on the know-how cultivated through the series' development to date. The panels used are double-sided. The entire surface of the screen, sides, and reverse side are painted. The same color as the screen background is also applied to the sides. The screen was pre-painted by undercoating and scraping to destroy the wood grain, and then painted in over 20 layers, including partial and solid layers. Then, grinding with water-resistant sandpaper is repeated until a finished screen is found. The slit on the back of the work is a ventilation duct within the panel, but pins and hooks can also be hooked during installation. Also, the smooth matiere of the grinding process allows the work to be wiped clean with a dishcloth or other cloth.
