Kimio Tsuchiya's Moon is a collection of 15 wedge-shaped chips cut from tree trunks about to be felled. They are chopped out in this way so as to control the direction a tree falls. These 15 chips belong to a handful of species such as Maku and Japanese cedar that are being felled for Japanese industries. Presented in an arc across the wall the chips vary in shape, from a slim crescent to a full circle, and illustrate the phases of the moon as it moves through each month. Moon, like Landscape in silence (Acc. no. 1996.224), is about loss. In this case it is directly associated with the natural world and refers to the interruption of the life cycle of the trees. As in much of Tsuchiya's work this sculpture discusses issues of both loss/destruction and continuity/survival.

Moon incorporates other timescapes. The 15 wedges are also symbolic metaphors for time which alludes to the cycles of rising and setting. Moon is an exploration of time and its relationship to a material world. Contained in this sculpture is the artist's fascination with making work that can express notions of the metaphysical, works that can encapsulate an abstract yet real quality, such as time, by using familiar materials and subjects that act as touchstones.
