About Planthoppers

It is during the summer months that planthoppers (also called leafhoppers) are often found in tea gardens. They are tiny green insects that bite the leaf and cause it to react to protect itself. Through this defensive reaction, the tealeaf emits a specific chemical that produces a unique scent. For this tea reacting leaf from Yabukita bushes is employed.

About the climate

Surroundings and environmental circumstances: Yōichi’s farms are situated in this central area on the Kyūshū mountain range, at an altitude of 600 to 650m above sea level. In summer it is cool, and in winter this region is treated with good amounts of snow. The temperature differences between day and night are large, while most mornings produce a thick mist over the mountains. These are all features that are specific to mountainous areas and that – in contradiction to flat areas – have always been considered more beneficial to the growth of tea, summer and autumn vegetables and rice.
