le polyrythme de la pluie

"The polyrhythm of rain" points to rain not as singular event but as overlapping cadences, where droplets at varied scales and intervals build a layered visual rhythm. Compositions in this vein typically dispense with horizon and ground, treating the picture plane itself as a curtain of weather, with [bokashi](/glossary/bokashi) gradients shifting tone from saturated to pale without visible break to register atmospheric depth. The musical metaphor of the title accords with the European modernist vocabulary that runs through Kasai's titling practice — French throughout — and reflects his post-1978 training at the École des Beaux-Arts after graduating from Tokyo Gakugei University. The print belongs to his sustained engagement with rain and water, the subject that succeeded his earlier garden and architectural elevations and has anchored his output for several decades. The technical demand lies in holding smooth bokashi transitions across a field interrupted by the linear marks of rain itself.
