Introduction of Newly Published Book “Japanese Black Tea Book” by Kei Okamoto Kei Okamoto, who runs a Japanese black tea specialty store and is known as a seminar and black tea instructor, has published "Japanese black tea book". Parade Co., Ltd. (1400 yen). Mr. Okamoto and I traveled to Sri Lanka together, and he is a very enthusiastic tea researcher. Easy to understand, Mr. Okamoto's unique commentary is written as a new tea manual. I would like to support Japanese black tea so that many people drink it and spread it around the world. We recommend that you read it.
