In cases the facility has deemed dangerous, the erection of tents may be prohibited even when reinforced.

Customer feedback


During the match our ball got stuck on the roof of the locker or futsal courts. What should I do?

Our staff will retrieve it for you. Please notify the front counter at the clubhouse.

Guests at the facility (especially high school students) have poor manners when using public transportation. What can I do?

When receiving a complaint, we find out the name of the school and immediately inform the appropriate staff about the nature of the complaint as well as ask for assistance in improving student behavior. For guests coming by public transportation, we also address manners at the reception desk.

There aren't enough areas for spectators to find shade from the sun.

Since we first opened, we have received feedback from a large number of guests regarding protection from the sun. In our first year, in order to provide some reprieve from the sun, we erected fixed tents, but these could not be used during times of strong wind. At that time, we were unable to fully meet our customers needs, but from 2011 we have established permanent fixtures to offer protection from the sun.

When applying on OPAS, it is not clear that a separate fee is charged for lighting.

Now when applying from OPAS, we have provided a notice displaying that lighting fees are separate from facility fees.

We would like you to do something about the traffic jams that occur when leaving the parking lot for big sporting events

In order to provide for smoother departures after competitions, we have installed ticket machines at our parking lot exits as well as dispatched supporting staff to handle parking fees.

The protective netting for the indoor futsal fields is close to the touch line making it dangerous for guests.

Previously, we had installed moveable protective netting, but in consideration of safety we have changed these to curtain-style netting. When using 3 fields together, please contact the front desk about removing the wires.

I would like to nurse my child. Do you offer nursing facilities?

The restroom is at Rocker House 5. Please feel free to use. The club hous also provide baby bed, if you want to use, please come check with the reception.
