At YNU, some 600 researchers conduct research in various fields and create and apply knowledge as an “international focal point of practical scholarship” that can contribute to the welfare of people in Japan and beyond, as well as to the sustainable development of society.
In addition to individual research, to promote collaborative research between researchers at YNU and at other institutions inside and outside Japan, 8 units have been formed at the Institute of Advanced Sciences and 24 research projects have been recognized by the Research Initiative and Promotion Organization as YNU Research Centers. Through this framework, focus is being placed on research in fields with high societal demand, academic fields, fields that are highly ranked socially or academically, and pioneering fields.
Furthermore, YNU has signed academic exchange agreements with over 140 universities around the world and about 300 researchers are accepted to YNU from universities outside of Japan every year.
YNU is in the top ten in Japan in the following fields for total number of selected projects of “Grants-in-Aid for Scientific Research (KAKENHI)”*1 in FY2018-2019.*2
*1 “Grants-in-Aid for Scientific Research (KAKENHI)” are competitive research funds that are intended to significantly develop all scientific research (research based on the free ideas of the researcher), from basic to applied research in all fields, ranging from the humanities and the social sciences to the natural sciences. The grants provide financial support for creative and pioneering research after peer review.

Let there be light: Synthesizing organic compounds
Results published online in the Journal of Organic Chemistry on July 19, 2019
Prof. Kiyoshi Honda, Dr. Yujiro Hoshino, Dr. Kenta Tanaka (Faculty of Environment and Information Sciences) and their team have developed cost-effective and milder synthetic routes to create oxygen heterocycles by focusing on a method involving the design of photo-sensitive carbon-based salts. They added the salts to two types of compounds, which form a ring once they react, and irradiated the combination with green light, producing a high yield of oxygen heterocycles. The researchers envision the expansion of the use of various visible-light-driven reactions in the future, and plan to continue contributing to it.EurekAlert!
Researchers teleport information within a diamond
Results published online in Communications Physics on June 28, 2019
Prof Hideo Kosaka (Faculty of Engineering) and his team have, using carbon isotopes in a diamond as a quantum memory, successfully teleported quantum information into an otherwise inaccessible space without revealing or destroying the stored information for the first time in the world. The study has big implications for quantum information technology - the future of how sensitive information is shared and stored.EurekAlert!
Shedding light on how the human eye perceives brightness
Results published online in Scientific Reports on May 20, 2019
Prof. Katsunori Okajima (Faculty of Environment and Information Sciences) and his team are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of visual environment. This ushers in a new understanding of the biology of the eye and how visual information is processed. The findings could contribute to more effective therapies for complications that relate to the eye, and serve as the basis for developing lighting and display systems.EurekAlert!
Laboratory study paves way for new approach to treating hair loss in humans
Results published online in Biomaterials on May 9, 2019
Prof. Junji Fukuda (Faculty of Engineering) and his team have developed an efficient method of successfully generating hair growth in nude mice. Compared to other methods, their new collagen-enriched hair bead (bbHFG) approach produced a high rate of hair generation four weeks after being transplanted onto the skin of the mice, and gene expression for almost all the hair producing gene markers was greater in the bbHFGs. The new method can be scaled up and therefore shows great potential for clinical applications in human hair regenerative therapy.EurekAlert!
Another Step forward on universal quantum computer
Results published online in Nature Communications on August 13, 2018
Professor Hideo Kosaka (Faculty of Engineering) and his team have demonstrated nonadiabatic and non-abelian holonomic quantum gates over a geometric spin qubit on an electron or nitrogen nucleus, manipulating purely the geometric phase with a polarised microwave in a nitrogen-vacancy centre in diamond under a zero-magnetic field at room temperature. They have also demonstrated a two-qubit holonomic gate to show universality by manipulating the electron−nucleus entanglement. The universal holonomic gates will enable fast and fault-tolerant manipulation for realising quantum repeaters interfacing between universal quantum computers and secure communication networks.EurekAlert!
The future of electronic devices: Strong and self-healing ion gels
results published online in Advanced Materials in July 31, 2018
Prof. Masayoshi Watanabe, Dr. Ryota Tamate (Faculty of Engineering) and their team, in collaboration with researchers of the University of Tokyo, have designed an ion gel with excellent toughness and an ability to self-heal at ambient temperature without any external trigger or detectable change in the environment such as light or temperature. This new class of material has promising potential for future applications in the area of flexible electronics – to create self-healing electronics in particular.EurekAlert!
