<lora:training_2617621-20260829142806970:1> z1os_onsen, A richly detailed cinematic anime scene of an empty Japanese onsen built inside a broad natural mountain grotto behind a luminous waterfall. Viewed from eye level on the front-left wooden walkway, the wide three-quarter composition looks diagonally across an irregular turquoise thermal pool toward the bright cave opening and a misty cedar valley. Thin veils of falling water glow in cool morning light. Warm lanterns, a cedar bath pavilion, timber rails, submerged rocks, small water outlets, folded towels, wooden buckets, moss, rich wet stone textures, rising steam and waterfall mist create a peaceful hidden-sanctuary atmosphere.
