Bericht vanuit de ADA nieuwsbrief:

ADA new website that has been postponed to release finally opened to the
public on Wednesday, 12 November. The switch of the access to the new website
is going to be done sequentially so it may take time to switch display
depending on your area. If it would not be switched, please take a pause for a
while and try again.

Unfortunately, it is temporarily available only in Japanese.
The English and Chinese versions are currently under construction and closed.
We’re sorry for the inconvenience, but please be patient and wait for our
brand-new English and Chinese websites, releasing in this winter.
We appreciate your support!
