1. American Prime Beef Chuck Roll, Sukiyaki Cut

Image: Kosuko
In Japan, there are grading systems for domestically produced Wagyu beef such as A3 and A5, but in the United States, there is also a grading system established by the U.S. Department of Agriculture, and "Prime" is the highest grade within that system!
Lately, it's become much more affordable than it used to be. It's only about 250 yen per 100g! I'm always amazed by Costco's incredible value for money.
Although it's sliced very thinly, the quantity is consistently just under 2kg, so it usually costs around 4,000 yen. It's cut thinly and wide (each slice is over 20cm long, so it's difficult to neatly separate them one by one!).
The taste was... absolutely delicious! It's different from Wagyu beef, and you can really savor the robust flavor of the lean meat. It's also easy to use in various dishes, so I think it's more versatile than beef specifically for yakiniku (Japanese BBQ)!
<Here's a good point!>
- USDA's highest rating, "Prime"
- Since it has never been frozen, the taste will not deteriorate even if you freeze it in small portions.
- It's easy to adapt to dishes like sukiyaki, nikujaga (meat and potato stew), stir-fries, and gyudon (beef bowl).

2. Special Family Platter (50 pieces)

Costco is known for its meat, but their sushi is also popular. The "Special Family Platter" is a deluxe version of their familiar "Family Sushi Platter." Looking at the price alone, it's certainly not cheap. However, it lives up to its "special" name; the ingredients are luxurious!
One of my favorite items on the menu is "Kagoshima Prefecture and other fully farmed fresh bluefin tuna medium fatty cut." With its melt-in-your-mouth texture, you can fully enjoy the refined flavor and sweetness of the fat, which is not overly rich, with just one bite.
Most sushi platters tend to include filler items, but here, every single piece is main-course worthy!
<Here's a good point!>
- Fresh bluefin tuna medium fatty cut with plenty of fat! And plenty of salmon roe marinated in soy sauce, which has seen a significant price increase.
- The portions are huge and incredibly thick.
- The variety, freshness, fat content, and size of the ingredients are all extremely satisfying.

3. Menissez Petit Bread (24 pieces)

The most distinctive feature of Menissez Petit Pain is that it is sold when it is about 80% baked.
Sprinkle lightly with water and bake in a preheated oven at 200-220°C for about 10-12 minutes! You can also use a toaster oven with a temperature setting (make sure to preheat it in that case as well).
When baked, the surface becomes incredibly crispy and crunchy, while the inside remains moist and pleasantly chewy. It's simply delicious even eaten plain! The flavor is quite salty. It also pairs perfectly with butter.
Considering this bread costs only 21 yen each, it's a real bargain. Freshly baked bread always feels special, and it's nice to be able to enjoy it at home.
<Here's a good point!>
- You can enjoy freshly baked French bread from France right in your own home oven.
- It has a long shelf life at room temperature. Since it's divided into four equal portions of six pieces each, there's no need to freeze it, saving space in the freezer.
- The price per item is reasonable.

4. Lindt Lindor Truffle Chocolate Assortment (4 varieties) 600g

Lindt Lindor is a traditional Swiss chocolate maker. However, this chocolate is quite expensive elsewhere. It is sold in sets of 2 or 6 pieces.
In that respect,
Opening the box reveals sparkling, round candy-wrapped packages. The box contains 600g and a total of 48 pieces: one each of milk, dark, hazelnut, and white chocolate.
*The total number of items and the number of each flavor may vary depending on the package.
With its two-layer structure, the slightly firm chocolate coating on the surface cracks with a satisfying crunch, releasing a creamy truffle chocolate filling that fills your mouth and leaves you utterly delighted! One piece is enough to satisfy you with a cup of coffee, making it a chocolate that, in a good way, prevents you from overeating.
That's right! If it's cold, the unique melt-in-your-mouth texture will be lost. If you're storing it in the refrigerator, let it come to room temperature before eating!
<Here's a good point!>
- You can find classic European souvenir chocolates at a great price at Costco.
- The sparkly, round packaging is adorable.
- A rich, creamy, melt-in-your-mouth texture. The creamy chocolate overflows, filling your mouth and leaving you utterly captivated.

These are popular disinfectant cleaning wipes from Costco. The box contains four packs: two of each of two different scents. The blue ones have a fresh air scent, and the yellow ones have a lemon scent.
The packaging states that it can be used to clean kitchens, bathrooms, toilets, car interiors, outdoor furniture, and delicate electronic equipment such as telephones. It can also be attached to your existing floor wiper for floor cleaning.
The sheets are made of Tencel, which is strong, doesn't tear easily, and won't dissolve when washed. The lemon-scented version has an embossed surface on one side, making it ideal for cleaning stubborn grease stains on gas ranges and range hoods!
This product is incredibly helpful for daily household chores, as it effectively removes dirt and even disinfects.
<Here's a good point!>
- These disposable sheets are soaked in plenty of cleaning solution, so you can wipe and clean anywhere with just one sheet.
- It can also be attached to a floor wiper for floor cleaning.
- It's especially effective against grease and is highly recommended for kitchen cleaning.
