"Hayabusa2" is a Japanese asteroid explorer launched on December 3, 2014 traveling to “Ryugu” and will return to Earth in 2020. During its six year voyage, Hayabusa2 aims to complete technically challenging missions to bring scientifically valuable FRESH soil samples of Ryugu.

In June 2018, Hayabusa2 will arrive at Ryugu and start great missions.
Its predecessor Hayabusa brought soil samples back from the S-type asteroid Itokawa. The samples revealed the origin of the meteoroid entering to Earth.
This time, the FRESH soil samples of C-type asteroid brought back by Hayabusa2 are expected to contain organic matter and water. The samples brought by Hayabusa2 may reveal the origin of sea water and life on Earth.

What is “Sugo-Haya2”?

We, "Project Sugo-Haya2" created the Japanese traditional game Sugo-Roku that simulates the Hayabusa2’s round-trip voyage to the asteroid Ryugu. It is “Sugo-Roku Hayabusa2”, whose nickname is “Sugo-Haya2.” The route on the “Sugo-Haya2” game board from the start to the goal simulates the process of the voyage and explains its mission well.

Through playing the game of Sugo-Haya2, you acquire a chronological bird’s eye view of voyage, learn about the interesting mission, and experience the challenges of Hayabusa2.
“Sugo-Haya2” has its own rules and characteristics that reflect Hayabusa2’s characteristics.
The routes reflect the voyage of Hayabusa2 and the players can learn its schedule. There are missions on the routes to the goal and the players can gain knowledge about the Hayabusa2’s missions. The degree of difficulties of the mission on the Sugo-roku simulates the actual level of challenges of the mission of Hayabusa2.

How to play Sugo-Haya2

Sugo-Haya2 is suitable for playing with 4 or 5 people. Everyone, from children to adults, can play and enjoy together.

Each player rolls a dice and move the number of squares that the rolled dice shows.

A player has to follow an instruction on the yellow-colored mission square if there is any available on the square he/she stops.
- On pink squares, you have quizzes to answer.
- On blue squares, you learn interesting knowledge
- Red squares mean “Danger”

The goal of Hayabusa2 is not only to come back to Earth, but also to bring lots of valuable samples back. Finally, the winners of Sugo-Haya2 are determined by the total numbers of samples brought back at the goal.
