As the third-generation owner of Osada-en Honten, Kaori Osada handles public relations and design. She was once active in the beauty industry, and that experience is the driving force behind her work to open up new possibilities for Japanese tea, such as developing tea soap and face packs. Kaori sees tea not merely as a "drink" but as a source of beauty ingredients grounded in dermatological knowledge and as a cultural experience that engages all five senses. While protecting the tradition of tea, she keeps pursuing "tea that fits into today's lives" – from Japanese-style black tea to stylish tea bags that suit modern needs.

Kaori is especially focused on offering "experiences" to younger generations. In the nerikiri-making workshop she teaches herself, participants make seasonal Japanese sweets and enjoy whisking their own tea, widening the circle of a tea culture that once felt intimidating. The refined packaging she creates together with the company's designer also makes young people think "this is cool" and pick it up. The connections that form between guests through these experiences, and the calm time spent around tea, are exactly the "rich life with tea" that Kaori treasures.

Thanks to the worldwide matcha boom, Osada Seicha's products have now spread overseas. Kaori hopes to use this momentum in reverse, helping young people in Japan rediscover the value of Japanese tea. Looking ahead, she is considering "tea tourism" in cooperation with the local shrines and rich nature of Morimachi, so that the whole region can celebrate its tea culture. Her challenge continues: carrying the spirit of hospitality that begins with a single cup of tea from Morimachi to the world and to the next generation.
