z1os, ultra detailed. An empty traditional Japanese outdoor onsen faces a colossal tornado at close range, viewed from a low diagonal angle beside the stone bath. Violent suction lifts the hot spring water into towering curved sheets, twisting arcs, flying droplets, and dense mist drawn toward the dark funnel. The bath churns beneath a shattered timber shelter as roof fragments and wooden debris whirl through the storm, distant pine trees bend in the wind, lightning cuts through blue-gray clouds, and a warm lantern glows across rain-soaked stone, ultra-realistic cinematic disaster scene, dramatic volumetric lighting, cold cyan and charcoal palette, epic scale.
