William Tussles abut over which route to connect the JR Hohi (isn’t it fun to say “Hohi”?) line to Kumamoto Airport, particularly whether an Ozu line or a Sanrigi line. Issues are distance and potential usage. I’d go with the Sanrigi line. It’s closer to the new fabs being built there, closer to many who would use the line from outside the city, and closer to the athletic park. It would be nice to see it completed within my lifetime.
