Is this tuna good for sushi?

I’m hosting a hand roll dinner party for a bunch of college students this weekend and was thinking of picking up this frozen tuna from my local Korean supermarket since the cuts in the sashimi section are close to double the price. The bags are dated early September they’re about a month old at this point.

I’ve watched vids on people using a salt water bath in thawing frozen tuna, but would appreciate any advice on working with the frozen stuff.
