Thanks for the responses!
Yeah, I couldn't find anything that was short-grain, but I've read where others have said Kokuho Rose works well. I did see some medium grain jasmine rice, but I figured a sushi rice might work better.
I think that's my issue right now. The bucket is full to the top, so I had to pack it in a bit. I'll poke some holes down into it.
I don't have a sous vide setup, but I can move it someplace warmer.
Once it liquifies, I do plan on moving it to a short secondary fermentation with an airlock and some sparkolloid to clarify it. Is that a wise idea?
Sho Chiku Bai sweet rice is good. I use it for some types of regular Chinese cooking too.

You can get it at the asian markets. I’ve seen it on Amazon and Walmart too.
If you have another bucket, you could split the batch between the two and loosen it up.
If you don’t have a sous vide setup, you can use a water bath with an aquarium heater. I’ve done that for yogurt before.
After a couple weeks at 85F, you can let it go for a another 3 months or so to ferment completely. You can go shorter, but the alcohol and flavor will not be as developed. You can go longer than 3 months without problem, even on the lees without filtering.
Airlock is not required, but you can use one if you prefer after the first couple weeks. Just make sure the batch is protected from fruit flies and evaporation.
Fining agents are not necessary. You can cold crash if you like. The traditional process just relies on straining, pasteurizing, and aging to clarify.
After the initial 3 months, you can transfer the rice wine to a large container for bulk aging. Use a slightly loose top that allows a tiny bit of air exchange without letting bugs to get in. Over time, this allows the wine to oxidize and darken slowly like with sherry. This is part of the process to turn regular huang jiu to Shaoxing style wine.
I just used a little plastic wrap and a loose fitting stopper. Traditional uses leaves, clay, and fabric or paper to make a semi permeable seal.

Here’s a pic of my Shaoxing style wine, on the left, after about 4 years of aging compared to a store bought premium Shaoxing on the right.
