The significance of RSJ as part of Kashiwa-no-ha Smart City

■Located in Kashiwanoha, with easy access from central Tokyo and home to many educational and research institutions and companies

The Tsukuba Express Line provides easy access to central Tokyo, only about 30 minutes away. RSJ is located in a positive environment where educational, business and research institutions, including Chiba University and the University of Tokyo, are concentrated. The opening of RSJ will further advance this accumulation of educational institutions.

■Will help realize the Kashiwa-no-ha International Campus Town Initiative, aimed at the creation of an international academic and research-focused city through public, private and academic collaboration

The “Kashiwa-no-ha International Campus Town Initiative,” sets out guidelines for neighborhood creation developed by Chiba Prefecture, Kashiwa City, Chiba University and the University of Tokyo, along with local residents. The goal was the creation of an international academic, educational and cultural space to implement cutting-edge, self-sustaining neighborhood development through public, private and academic collaboration, based on a policy of enhancing the basic educational environment to develop personnel who will be active on the forefront of global developments.

Infrastructure for an international education has been put in place with the recent opening of RSJ, one of the world’s top schools. In addition to existing world-class academic institutions such as the University of Tokyo, Chiba University and the National Cancer Center, new research institutions, companies, and new residents from both Japan and around the world, are expected to come together in Kashiwa-no-ha Smart City. Further, this initiative can contribute to the concentration of international human resources in Tokyo and Japan as a whole, thus improving the international competitiveness of Japan itself.

The UK’s Rugby School is also known as the birthplace of this ball sport, and RSJ itself opened on the 200th anniversary of the game’s birth. As the location of the home stadium for the NEC Green Rockets Tokatsu, Kashiwanoha has deep ties to rugby, and in the past the New Zealand national rugby team was provided with pre-tournament support there. RSJ is equipped with a rugby field that meets international standards, which will lead to the promotion of sports, globalization and community vitalization through rugby.

■Kashiwa-no-ha Smart City will be a breeding ground for innovation, turning out individuals capable of playing an active role on the world stage

Mitsui Fudosan is working to help solve social issues through neighborhood creation, and to date has been responsible for providing not only buildings themselves, but spaces and communities.

In this sense, Kashiwa-no-ha Smart City also serves as a new site for demonstrating a variety of innovations using the city itself as a platform. With the opening of RSJ, the goal is to see an even greater diversity of people utilizing this platform to form a variety of communities, turning Kashiwa-no-ha Smart City into a breeding ground for innovation.

  • Kashiwa-no-ha will develop and turn out world-class human resources under the “whole person education” advocated by RSJ. This aims to nurture globally active, next-generation leaders who will shape the vision of the future. This is the goal of Kashiwa-no-ha Smart City.
  • The initiative aims to create new industries and cultural values by deepening collaboration and interaction among nearby educational institutions, including Chiba University and the University of Tokyo, as well as businesses, research institutions and the local community. In addition, putting in place infrastructure capable of providing a global education is expected to draw an even greater accumulation of human resources and foreign-owned businesses from regions around the world, with a focus on Asia.
  • Kashiwa-no-ha is currently working to develop as a creative site for innovation that will drive new industries. At the same time, as a variety of community activities move forward, including promoting collaboration between academia and business as well as the participation of residents in neighborhood development, it will be important to nurture the next generation of human resources involved in this sustainable neighborhood development. Developing global-level talents in Kashiwa-no-ha who will take on “sustainable development and innovation” will lead to the formation of a sustainable city.
