Póster: Posada onsen

A serene Japanese onsen inn poster in a clean centered layout, a traditional wooden ryokan building with curved tiled roofs under a rising mist, a steaming outdoor hot spring pool with smooth stones and a single red maple branch, Mount Fuji faint in the distance, paper lanterns glowing softly along the walkway. Delicate brush-style serif headline in deep vermilion reads '湯治宿', with thin vertical Japanese text columns on the side and a small gold crest below. Palette of warm wood brown, indigo blue, vermilion red, mist gray and snow white. Printed on smooth washi-style paper with a subtle woven texture and gold edge accent. The poster hangs on a sliding shoji screen in a tatami room, a low table with tea set beside it. Soft warm lantern light from the upper right, dusk indoor quality, gentle glow on the paper, soft diffused shadow. Medium shot, straight-on view, refined texture detail, 4k
