Kiyoto Maruyama is one of two remaining “Penki-eshi” (Sento painters) in Tokyo. Today he is painting the back wall of Fujino-yu, but as we arrive he climbs down from the scaffolding, walks through the coffee cans and paint tins to sit down in front of us. His track pants and slip on canvas shoes are coated in a dense patina of blue and white paint and behind his seated silhouette, today’s wet, half-finished portrait of Mt. Fuji is drying in the afternoon sunlight.
