Waves of petals

The title names the visual conceit of fallen cherry blossom petals drifting across a surface in wave-like patterns — the phenomenon Japanese poetry calls hanafubuki, "flower blizzard." Kasamatsu would render this through layered impressions of pale pink and white pigments on washi, with unprinted paper potentially providing a luminous ground beneath the petals. The composition probably treats the petals as a moving plane rather than as individual blossoms, dissolving discrete forms into rhythm. Cherry blossom subjects connect Kasamatsu to the broader Tokyo print tradition of his teacher Kaburagi Kiyokata and fellow Kiyokata students Kawase Hasui and Ito Shinsui, all of whom produced sakura designs. Kasamatsu's interpretation here favors atmospheric effect over the figural staffage that often appears in Hasui's spring scenes.
