TANAKA Memorial Foundation Announces Recipients of Precious Metals Research Grants

TOKYO, Mar 31, 2026 - (ACN Newswire) - The TANAKA Memorial Foundation’s Representative Director, Hideya Okamoto, announced the recipients of the FY2025 Precious Metals Research Grants.

Following a rigorous screening process, this year’s Ichiro Tanaka Awards, for 3 million yen each, were presented to Professor Takanori Iwasaki of Kyushu University and Professor Toshinori Fujie of Institute of Science Tokyo. In addition, four research projects received the Innovative Precious Metals Award, and five KIRAMEKI Awards were presented.

The TANAKA Memorial Foundation undertakes programs designed to foster developments in new precious metal fields while contributing to the advancement of science, technology, and socioeconomics for the overall enrichment of society. The research grant program was launched in FY1999 and has continued each year since with the goal of supporting the various challenges of the “new world opened up by precious metals.” With “Forging a better tomorrow with ‘Hirameki’ and ‘Kirameki’” adopted as the catchphrase, applications were invited for research and development themes that contribute toward the continued creation of a better future using the creativity of researchers and the potential of precious metals. A total of 244 applications were received for this year, the program’s 27th year, and a total of 27 research grants for a combined total of 19.8 million yen were awarded.

The names of the recipients of the Ichiro Tanaka Award, their research, and the reasons for their selection are below.

Ichiro Tanaka Award
Professor Takanori Iwasaki of Kyushu University
Chemical Recycling of Recalcitrant Polymer Materials Using Hydrogen Transport
This research seeks to address the degradation of polyurethane using a proprietary precious metal complex catalyst. It has been demonstrated that polyurethane can be decomposed by hydrogen gas. As the development of chemical recycling methods for polyurethane used in cushioning materials such as automotive seats and mattresses is essential for promoting the reuse of waste plastics, it was highly rated as research and development that makes a significant contribution to the realization of an environmentally sustainable society.

Ichiro Tanaka Award
Professor Toshinori Fujie of Institute of Science Tokyo
Development of Biodegradable Nanosheet Electrodes Composed of Inkjet-Printed Gold Wires and Their Application to Plant Health Measurement Systems
This research measures changes in the surface potential of plant leaves in real time by formation of an array of gold electrodes on a polymer ultrathin film substrate. By investigating materials with minimal impact on living organisms, it is expected that raw data can be obtained from plants. Furthermore, the research was highly rated for its potential to reveal not only changes in bio-surface potential in plants but also changes in various conditions in animals.

Four Innovative Precious Metals Awards, 16 HIRAMEKI Awards, and five KIRAMEKI Awards were also granted. The recipients and an overview of the Precious Metals Research Grants are indicated below. Applications for the FY2026 research grants are scheduled to open in the fall.
