Where can I buy an ice luge?

I realize this sounds ridiculous, but here we go. I really want to have an ice luge* at a party I’m hosting in a few weeks and my Google-fu has failed me— though I did learn about a pretty neat ice sculpting school. So, is it possible to buy/order one anywhere in Tokyo?

• if you don’t know what an ice luge is, it’s a large ice sculpture/block in which you pour alcohol at the top of it, and it flows down a “luge/channel into a waiting mouth.

Thanks!
