In the aged society in Japan, social security cost has increased a lot, including medical cost. This trend will not stop for the next several decades. On the other hand, because of the low birth rate, the numbers of workers will decrease. In 2050 when the current students will be active in the society, 1.2 workers support 1 elder person. Kenji Watanabe seminar deals with ME-BYO characterized with vague unhealthy condition. For ME-BYO improvement, we have developed YAKUZEN recipe, YAKUZEN tea, Beauty and Health Diary which supports womens health, et.al. The students are active for the preparation of a sustainable society in 2050.
