Konami has cancelled the Live Stream for the Nagoya YCS Japan event, why is not explained.

Of further note:

The YCS will be held as scheduled.

Masks will be distributed to those who wish to use them but stock is limited.

Alcohol disinfectant will be available at the entrance as well as throughout the venue, so attendees are heavily encouraged to wash their hands.

If a player feels sick or ill, they are advised to not participate. Those who seem adversely ill will have participation refused.

Players are to follow all staff instructions. Those who refuse will be denied event participation.
