Deep Affection and Responsibility in One Drop

Surrounded by 4000 hectares of green tea estates, we OISE Inc. is located at 300meeters above sea level, overlooking ISE BAY. “ISE-CHA” green tea leaves, harvested in the area of ISE Bay, have more than an 1000 year history and hold a 50% market share of both types of shade grown tea called“GYOKURO” and “KABUSE-CHA.” Those are differentiated products in terms of their cultivation. The leaves are covered to block out sunlight for 20 days before harvesting.
