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.

More cyanobacteria could be lurking within marine hosts

A species of cyanobacterium has a worldwide distribution and significantly fewer genes than its close relatives, whole-genome sequencing has revealed.

Photosynthetic cyanobacteria survive in a wide range of marine environments. While much research has been done on their free-living form, little is known about those co-existing in a symbiotic relationship with other organisms.

Now, DNA investigations by researchers at the University of Tsukuba and colleagues in Japan have improved our knowledge of a poorly described cyanobacterium, dubbed OmCyn, which lives within a species of marine plankton.

Their analyses revealed OmCyn DNA is widely found in the world’s oceans. Also, its genome contains significantly fewer genes than most of its relatives, probably because of its residence within the relatively mild and stable environment of its symbiotic partner. 

These findings provide crucial insights into cyanobacteria diversity and evolution, and suggest that other symbiotic cyanobacteria lineages may be waiting to be discovered.
