Web Hosting - "A record" pointing at incorrect place

I am helping my debate club fix their website.

I believe that ownership of the domain lapsed. The website configuration and account are on bluehost.com, but according to this whois:

Some Japanese company called GMO owns the registrar, or A record or something. (I'm not well versed with how this works). Bluehost tech support couldn't help me other than saying to contact GMO.

They don't appear to have any viable contact information; they have a webform but I didn't get a response through that.

I don't even need the domain to display anything useful right now, I just need it to stop displaying Japanese hormone stuff.

What can I do?
