About 70% of Japan is mountainous, so megaliths, cliffs, and rock formations are a common sight. Some are works of nature; others, of man. But with imagination, they are works of art. Our reporter visits a former quarry in Kanaya, Chiba Pref. He walks around sheer walls, is awed at the sight of huge stone Buddhas, and climbs a boulder lookout which leaves you weak-kneed. Our correspondent suggests a trip to Wakayama Pref. and a soak in a cavernous hot spring, overlooking the Pacific Ocean.
