Part of Masaji's extensive "Kukan" (Space) series, this thirteenth entry continues the artist's sustained investigation of spatial relationships through abstract woodblock printing. The Kukan series represents perhaps Masaji's most systematic body of work, with dozens of numbered prints exploring how carved and printed forms can create sensations of depth, compression, expansion, and void on a flat surface. By the thirteenth iteration, Masaji had established a visual vocabulary for these spatial explorations and was testing its limits, discovering what new configurations the basic elements of block, ink, and paper could yield. The Japanese word kukan carries architectural and philosophical overtones beyond the English "space," encompassing both physical volume and the Buddhist concept of emptiness that pervades Japanese aesthetics.
