They are! You need to download the Hacosco app. It's available for android - https://play.google.com/store/apps/details?id=com.hacosco.viewer&hl=ja
And iOS - https://itunes.apple.com/jp/app/hakosuko/id918422586?mt=8
Once you download it, just look for the Suiyoubi channel and you download the video. Chupacabra was the first song. Haven't seen it all yet but a website says 2 more songs will be added later on.
Edit: video was like a minute long. Disappointing they weren't full and no inclusion of Basho.

I think it's some sort of competition to get one of the Miku VR designs? Honestly I have no idea, if someone who can actually read Japanese can give us the gist of the page it'd be awesome.
Edit: Also looks like you can watch the Google Cardboard demo through their app as well. Additional Info.
