Selected by a leading investment specialist as a

“Good Company”

Kamakura Investment Management manages the publicly offered investment trust Yui Nii Ichi Zero Ichi, setting unique criteria for selecting “good companies” to invest in.
Tsumura was selected for inclusion in the portfolio as a “good company” that contributes to the healthy lives of people and extension of healthy longevity in 2010 when the investment trust was launched, and has continued to hold the status to this day.

Reasons for selecting Tsumura are not limited to simply its competitive advantage of promoting a global business as a specialist in Kampo, a niche market. More than that, the trust manager notes the company’s management philosophy of conducting correct business in accordance with the principles of nature, as represented by the phrase of “In the Spirit of Nature’s Laws,” as well as the corporate quality built under the management philosophy and that appear in the following forms:

  1. Autonomous organizational culture that encourages both the independence and mutual cooperation of employees
  2. Management policy of providing fair employment opportunities to those with and without disabilities
  3. Strong commitment to stable supply of high-quality Kampo products

These characteristics superlatively match the investment trust’s selection criteria related to “people.”
