Project is absolutely not dead but some infos are not up to date on coinmarketcap.
(Japanese are usually not very good / active on non-japanese sites)

Correct telegram channel link is on https://alismedia.jp (you can contact dev directly, but many spam "when moon ?" stuff)
New trello page : https://trello.com/b/BBhg390G/alis

Check their twitter as official source of infos. https://twitter.com/ALIS_media They make an english and japanese post every day.
They are currently doing some meetups in japan to talk about the project. Next one at Nagoya (tomorrow)

I don't think dev for the site has actually started (or the github is not yet public) they are still working on planning/design

They should update their company website soon

The fact they kept 50% of the token for them is discutable but it was clearly announced on the whitepaper.
The team being 100% japanese (without shady foreign millionaire investor ) is a good thing imho.

I have high hope for this project.
