Costco Siwin Japanese Style Sausage Review

Costco offers a fairly large selection of hot dogs and sausages. Usually it’s pretty clear what the best way to serve one of these is, but when I saw the pack of Siwin Japanese Style Sausage at Costco, I wasn’t sure what I should do with them. Are they best served on a bun like a hot dog or do they work as the protein in a fancier meal like some higher-end sausages do?

Today I’m reviewing the Costco Siwin Japanese Style Sausage. This is a product that’s fairly new to my Costco and I was curious about what a Japanese sausage tastes like, so I picked them up.

Other sausage products from Costco are the Costco Kirkland Signature Beef Wieners, Costco Prairie Creek Kitchen Beef Sausage Rolls, Costco El Monterey Egg, Sausage. Cheese & Potato Breakfast Wraps, Costco Olympic Craft Meats Garlic Sausage and the Costco Smokey River Meat Company Turkey Breakfast Sausages.

Location in Store

You can find these Siwin sausages in the deli department at Costco near the cold cut cuts, other sausages and cheese. The item number is 1435450.

I like these sausages! They remind me of a bit lighter-tasting hot dog. If you use them as a hot dog, they’re not as flavorful as other hot dogs I enjoy, but they’re still tasty. They definitely are more like a sausage in that the casing is quite thick, which I don’t love.

I can see using these as hot dog, but you could easily have them for breakfast or even serve them as a main with a side of rice and vegetables. Nothing really screams Japanese flavor to me other than maybe a slight sweetness that I can taste which differs from other sausages.

Although there’s cheese on the ingredients list, I don’t notice any cheese flavor personally. Overall, these sausages are tasty enough that we’ll finish eating our pack, but I don’t think they’re anything special or unique!

The 1.20-kilogram pack of sausages costs $13.99 Canadian at Costco.

The best before date on the Costco Siwin Japanese Style Sausages is about three months from the date we purchased them. The sausages need to be refrigerated. You can also freeze them if you won’t be using them until after the best before date.

No artificial color, zero trans fat and they’re made from pork raised without any added hormones.

To cook the sausages, you can grill, pan-fry or microwave them. They’re fully cooked, so you just need to reheat them. The sausages are made from 100% Canadian pork that’s raised without any added hormones.



There are 174 calories, 12 grams of fat, seven grams of carbohydrates, three grams of fibre, two grams of sugar, nine grams of protein and 600 milligrams of sodium in one sausage. The sodium is a little high, but less high than other sausages. For example, the Costco Kirkland Signature All Beef Wieners have much more sodium per serving!

For anyone following a gluten-free diet, good news! The Siwin Japanese Style Sausages are gluten-free! The ingredients list is pretty typical for sausage. I don’t love the soy protein and corn protein that’s added. If you’re health-conscious, I wouldn’t recommend eating these sausages daily!

I don’t absolutely love these, but they’re not bad! I thought they’d have a unique flavor, but they don’t. If you have an air fryer, I think they’d taste great cooked that way.

  1. Why is this product discontinued by Costco? I have been trying to purchase this product since I first sampled it at this store several months ago.
    Now after researhing the location of a store that carries it, I have found a store several kilometres from my location in the City.
    This store has about 200 units and will not be restocking.
    Is there any other outlet besides Costco that is carrying this ? I very much like this sausage for it’s taste as well as for it’s content.

  2. The thick casing you didn’t like is the important part of the Japanese style sausages. They love that crispy bites. That makes it “Japanese style” not any special flavour.
