Imagine walking into a cavern where the walls are lined with **towering crystals**, some as tall as a giraffe, others stretching longer than a city bus. Their translucent spires shimmer like frozen moonlight, jutting out in every direction. It looks like a fantasy scene from a science fiction epic — but it’s real. Hidden deep beneath the earth in northern Mexico lies one of nature’s strangest masterpieces: the **Cueva de los Cristales**, or **Cave of the Crystals**.

Deep within the forests of Tochigi Prefecture lies a place where myth and mystery echo through sacred halls. At first glance, Nikkō Tōshō-gū looks like any other stunning Shinto-Buddhist shrine—gilded, intricate, layered with centuries of craftsmanship. But step inside the Yakushi-dō Hall, look up, and clap your hands just once. The dragon will respond.
