Upgrade work at the Hanazono Rugby Stadium complex in Osaka Prefecture has not yet started, 5½ years after a related agreement was made.

The planned upgrades, featuring the construction of a new stadium by FC Osaka, is a condition for the third-tier J. League club to use Hanazono as its home ground.

The city of Higashiosaka, which hosts the stadium complex, renewed its agreement with the club by setting a deadline to complete the work.
