山中のトンネルと吊り橋：到着前の暗闇

Design a mountain museum approach in the manner of I. M. Pei's Miho Museum, staged as the Peach Blossom Spring parable — a curving stainless-steel tunnel bored through a ridge, then a single suspension bridge, then the building appearing suddenly across the valley. Compose a polished tunnel mouth reflecting the cherry trees behind the viewer, the bridge and a glass-roofed pavilion visible as a bright disc at the far end of the dark curve, forested Shiga mountains, mist in the valley, strong contrast between the dim tunnel and the bright opening, one-point perspective, 24mm lens, architectural photography, ultra photorealistic, 8K
