The Japan Archipelago, mountainous, volcanic, surrounded by seas, belongs to the temperate zone. In summer, it is hot and humid, and in winter, cold and snowy. The special characteristics of the climate in Japan are clearly distinguished seasons and the highest precipitation rate among the other temperate zone countries. That’s why the Japanese, who are agricultural people, have developed a keen sense of seasons, that has influenced our aesthetic consciousness and sensibility. We admire the nature; landscapes with flowers, dead and dry leaves and animals. However, sometimes it destroys our life completely; storm, thunder, earthquake, tsunamis, flood, eruption, and so on. We have always cohabited with cruel, dangerous and beautiful nature from ancient time.
