University of Tsukuba


The University of Tsukuba is located in the suburbs of Tokyo and is at the heart of Tsukuba Science City —Japan’s largest “science city,” which has 29 national research institutes and more than 200 private research organizations. The University operates on the principle that it is open to all.

The University of Tsukuba aims to cross the borders that separate a variety of organizations, such as those between nations, research institutions, and fields of study. The University’s network is expanding globally. In particular, the University has entered into eight campus-in-campus arrangements with universities in six countries and regions, thereby promoting close cooperative relationships between education and research. At present, the University hosts approximately 2,500 study abroad students from more than 110 countries and regions of origin.

Collaboration is essential in order to achieve high-quality outcomes with limited resources. As an example, the University is actively engaged in an exchange of talent and joint research that goes beyond the conventional university framework at nationwide joint-use institutes that encompass the four fields of computational science, marine science, plant science, and plasma research.

The joint research being conducted with the research facilities within Tsukuba Science City is expanding into drug development, robotics engineering, space medicine, plant breeding, astrophysics, and sleep science, as well as a wide variety of interdisciplinary areas, leading to a greater number of superior research outcomes than can be achieved on a university scale alone.

The University is also proactively engaging in the support of venture corporations. Thus far, a total of 141 companies have originated from the University of Tsukuba, including Cyberdyne, Inc.

A frontrunner in university reform in Japan, the University is creating a flexible education and research structure as well as a university system to meet the needs of the next generation. It aspires to be a comprehensive university, continuously meeting new challenges and developing new areas. The foremost mission of a university is to provide an environment that allows future leaders to realize their full potential. The University of Tsukuba gives students the opportunity develop their individuality and skills through an education that is backed by cutting-edge research.

Going pear shaped



The greater stability of pear-shaped nuclei can partially explain why large atomic nuclei split unevenly into a large and a small daughter nucleus, two nuclear physicists have found.

In nuclear power stations, large atomic nuclei such as uranium break into two smaller nuclei, releasing energy in the process. Interestingly, the two daughter nuclei don’t have similar masses: one is considerably bigger than the other. Physicists have long wanted to understand the factors that determine the relative masses of the daughter nuclei.

Now, a researcher from Tsukuba University in Japan and his collaborator have performed calculations that show that pear-shaped daughter nuclei preferentially form due to the strong repulsion generated by the electrical charge of the two fragments. This finding will help refine models of the nucleus and improve predictions of fission products.
