Profile
I am a researcher in Civil Law (Japan) and Comparative Contract Law (Civil law, Common Law, and Mixed Legal Systems). I have been a Lecturer in Civil Law, Contract law (in Common law), and Consumer law at the Faculty of Humanities and Social Sciences, Yamagata University (National University), Japan since October 2023. I have also been Invited Lecturer at the Centre for ELSI (Ethical, Legal and Social Issues) at The University of Osaka since July 2024. By way of background, from April 2020 to March 2023, I was granted JSPS Research Fellowship (DC1) and Grant-in-Aid for Scientific Research (No. 20J21047). From April 2021 to March 2023, I worked as a Project Researcher at the Principles of Informatics Research Division, National Institute of Informatics (NII), Japan. During the same period, I also conducted research as an Academic Visitor (Visiting Scholar) at the Faculty of Law, University of Cambridge, United Kingdom from 1 June 2022 to 31 October 2022 (*shortened, owing to COVID-19). I obtained LL.M. (Hitotsubashi University, Japan) in March 2020, and Ph.D in Law (Hitotsubashi University, Japan) in March 2023. I was a Fellow at the Faculty of Law, Kokugakuin University from April 2023 to September 2023. My main interests are in transplantation, conflict, and harmonisation of legal systems. My main research fields are in Japan (a Civil Law jurisdiction with a transplanted law), and sometimes in the United Kingdom (a Commonwealth-Common Law jurisdiction; for a comparison with the Civil Law System). Now, I'm committed to research into the Internationalisation of Contract law from a comparative law perspective, with a focus on Mixed Legal Systems. In detail, I discuss harmonisation of law, not only from the perspective of UNIDROIT, but also from a perspective of common law in the Commonwealth (e.g. Cross-jurisdictional references to case law as a persuasive authority from other Commonwealth common law jurisdictions). I then attempt to apply such principles of UNIDROIT to Japanese Law as transplanted law, using the Mixed Legal System as a buffer. In addition to this, I am also reconsidering the doctrines and works of Prof. Sakae Wagatsuma who was born in Yamagata (where the Wagatsuma Collection is held at Yonezawa, Yamagata) from such perspectives. As my other research interests, I am also interested in 'Law and Economics' and Juris-Informatics (which includes 'Crypto-Assets and Private Law'). <*Profile photo is at Sidgwick Site, University of Cambridge, Aug 2022; Originally taken by Mark Box, the Editor of `Humans of Cambridge' in Cambridge Edition.>
