"Scientific research is like training for me, as truth may only be reached after many failures in proving various hypothesis. Hope I can develop myself up through this training."

I had been engaged in nonclinical safety assessment for nearly 20 years, mainly on genotoxicity evaluation, in the pharmaceutical industry. I joined JT in 2017 and am mainly in charge of in vitro biological assessment of Reduced-Risk Products.

I have a PhD in agriculture and am a certified toxicologist of the Japan Toxicological Society.

"Science helps shed light on things nobody knew and resolve things that need to be tackled. I trust every research has something that makes people’s life better."

After PhD degree in agriculture, I joined JT in 2010. Since 2016, I have been involved in a project to consolidate various biological assessment results in order to assess the Reduced-Risk potential of the JT Group's proprietary products. I am now responsible for initiating new research projects, using state-of-the-art technologies.

"Truth can be one, but approach to identify it can be many. I believe ability of a scientist can be assessed by appropriateness of his/her methodology and evidence."

After obtaining PhD degree in agriculture, I joined JT in 2017. I have been conducting research on flavors for our products ever since. Current my work is to research the effects of aroma and taste substances on the human sensory mechanisms.

“Science is a tool to convert various invisible phenomena into simple concepts; these concepts can help interpret various independent results easily and also help predict outcome accurately.”

After various careers in tobacco research, which began in JT in 2001, I became involved in tobacco vapor products development in 2015. I obtained PhD in engineering and now I research the generation mechanisms of chemical compounds in vapor from products.
