In June 2025, Yamagata University announced the Benibana Sat Project (BSP), an effort to build and launch a CubeSat. The name comes from the safflower, the prefectural flower. Working with companies, students, and researchers from across the prefecture, the team is developing a 1U satellite, a 10-centimeter cube, and aims to launch it and begin operations by the end of fiscal 2028. A regional national university in Tohoku stepping into space development has drawn attention as a sign of how far Japan's space industry is broadening.

Starting From the Smallest Unit

A CubeSat is a standardized miniature satellite built in units of 10-centimeter cubes, with each unit weighing about 1.3 kilograms. Development costs drop sharply compared with conventional large satellites, which is what has let universities and small firms into satellite work at all. The 1U format BSP chose is the smallest size in the standard.

Small also means constrained. Available power and payload space are limited, and attitude control and communications demand careful design. Starting at 1U is deliberate: the point is to carry one satellite all the way from design to operations and gain that experience end to end.

Why Yamagata Is Looking Up

Part of the reason is national policy. The Cabinet Office's Basic Plan on Space Policy commits to supporting private companies and universities entering space development, which has widened the opening for regional institutions.

Another is the link to local industry. Yamagata produces cherries and rice, and agriculture is one of its main sectors. Earth observation from orbit can monitor crop growth and gather weather data, which gives the project a plausible route to returning something useful to the region.

The third is people. Nobukazu Kamei, the professor leading the project, frames it as industrial development under the Social Innovation DX endowed course, funded by a donation from the Mori no Gakko foundation, with the goal of establishing a base for space-related industry in Yamagata. BSP runs on three slogans, roughly "for Yamagata's industry," "people for Yamagata," and "energize Yamagata," and plans to make the university a hub for talent and technology while co-developing with local firms. Building a satellite is less the end in itself than keeping the companies and people who can build one inside the prefecture.

Toward a Launch by Fiscal 2028

The development team formed in 2025 around Yamagata University. Faculty and engineering students make up its core, with students responsible for design, manufacturing, and operations. The plan runs from basic design and skills acquisition through manufacturing and testing, with launch no later than fiscal 2028.

Update: In May 2026, a ground test model of Benibana Sat 01 went on public display at the Yamagata Prefectural Industrial Science Museum in Yamagata City. Visitors can see the 10-centimeter cube itself, making visible the stage the university and the Mori no Gakko foundation have reached with their partner companies in the prefecture.

Success would deliver more than a launch record. Students gain hands-on engineering experience with an actual spacecraft, and the data collected has applications in agricultural support and disaster preparedness. Local firms get an entry point into higher-value manufacturing, and the university gains research themes that require access to the space environment.

Where Japanese University Satellites Stand

Japanese universities have been building CubeSats for more than two decades. It began in 2003, when the University of Tokyo's XI-IV and the Tokyo Institute of Technology's CUTE-I (the institute is now part of the Institute of Science Tokyo) reached orbit on the same launch. Hokkaido University, Kyushu Institute of Technology, Tohoku University, and others have since put up satellites of their own.

Yamagata University's project adds another Tohoku node to that network. A regional university taking on frontier technology is itself a method for rooting skills and people in a place. That is the part BSP is testing.

In Japan, university-led space development is steadily expanding. How about in your country? What is the state of space development projects by universities or educational institutions? What do you think about regional universities taking on cutting-edge technology challenges? We'd love to hear your thoughts!
