Abstract
The Japanese have favored mushrooms as food and medicine for a long time, and developed many cultivation methods to satisfy their demand. Recently various and large quantities of mushrooms are imported from all over the world because of the developments in transport techniques and traffic network. Especially, the importation of the Matsutake (Tricholoma matsutake) is increasing in relation to its origin and quantity. These facts indicate that the Japanese have an inclination towards Matsutake, but the domestic supply is insufficient in comparison to the demand. The four distinct seasons of Japanese are reflected in the alteration of the kind and quantity of imported mushrooms. However, some mushrooms that appear in Japan and lend a variety to the Japanese table with the gourmet-boom are adopted and fixed to their table. Kansai International Airport, the first 24-hour available airport in Japan will be constructing its second runway in the near future. Due to this construction, the flight numbers and routes will be altered, and its effect and or influence are of great interest. On the other side it is important to ensure the food-hygiene of imported mushrooms concerning their variety and size.
