## About

The fund was established as the corporate pension vehicle for Eisai Co., Ltd., the Tokyo-based pharmaceutical company with a century-long operating history and a global footprint in neurology and oncology. Its mandate is straightforward: manage the defined-benefit obligations for current and former employees of the Eisai group. The wealth origin is exclusively the sponsor's pharmaceutical operating cash flows — there is no family wealth, no endowment, no external capital source. The fund's relationship with the Naito Foundation, a major Japanese medical-research philanthropy, creates an unusual adjacency between pension assets and scientific grant-making within the same corporate family. Asset allocation spans public equities, fixed income, and alternatives — the typical triad for a mature Japanese corporate pension. The fund reports exposure to natural resources, a category often bundled with commodities or infrastructure in domestic Japanese pension portfolios. Its PRI signatory status, secured in December 2019, requires annual reporting on responsible-investment practices across asset classes. Japan's Corporate Stewardship Code adoption in February 2018 places the fund among the early institutional adopters of structured engagement with portfolio companies. The more recent adoption of the Asset Owner Principles in February 2025 aligns the fund with the Japanese government's policy push to professionalize domestic institutional management and improve risk-adjusted returns for the country's pension sector. The fund operates from the sponsor's headquarters in Tokyo, with no disclosed separate offices. Team size and total assets are not publicly reported — consistent with the disclosure practices of most unlisted Japanese corporate pension funds that are not registered as discretionary investment advisors. The fund's participation in the Japan Climate Initiative adds a climate-policy layer to its existing ESG integration. Structurally, the fund represents the classic Japanese corporate pension model — sponsor-directed, conservative in disclosure, but increasingly subject to the same governance codes that have reshaped the Government Pension Investment Fund and larger peers. Its dual adoption of the Stewardship Code and Asset Owner Principles is uncommon among single-sponsor corporate plans of its generation. The Naito Foundation link, while not investment-related, creates a rare institutional bridge between a pension fund's parent and one of Japan's oldest private medical-research foundations, founded by Eisai's own founder.
