Just spoke to a woman at Herba Natural (2nd one - 1st needed some ESL courses), and she informed me that the green tea sold under the brand Royal King is grown in China, NOT Japan. I also emailed a missive, and await a reply from the company as well.
I purchase the tea at a very good price from a Chinese herb company in NYC, Kamwo. I buy 12 boxes at a time, 100 tea bags each...reference my previous post: 3 gallons iced tea per day...
