Suiraijin (Thunder God of the Sea)

Suiraijin (水雷神, 'Thunder God of the Sea') is a 1944 painting by Kawabata Ryūshi held by the Ryūshi Memorial Museum in Ōta, Tokyo, painted in the closing year of the Pacific War. The work belongs to the corpus of sensōga (war paintings) that senior nihonga artists were commissioned to produce by the wartime cultural authorities, and it has been the subject of continuing scholarly debate in the postwar period — at once an ambitious deployment of Ryūshi's signature kaijō geijutsu mode at full scale, and a politically compromised product of the wartime apparatus. The title fuses the traditional iconography of the thunder god (Raijin), a familiar figure in Japanese painting since the seventeenth century via the great Sōtatsu folding screen, with the wartime romanticization of naval torpedoes (suirai) as a kind of mechanized divine retribution. Ryūshi handles the subject in his mature mineral-pigment idiom, with the dynamic figure pushed against a darkening sea and the composition built for the large public exhibition hall rather than for intimate viewing. The picture sits alongside Bakudan Sange (1945) as one of the central documents of Ryūshi's wartime practice.
