7-Eleven Japan will begin a rolling nationwide release of its new product, “Chukashoba Tomita Supervised: Chilled Pork Mazemen,” starting Tuesday, April 14, 2026. This item is a collaboration with the legendary ramen shop “Chukashoba Tomita,” located in Matsudo City, Chiba Prefecture.
This product is a chilled “Mazemen” (a soupless style of noodles meant to be mixed) created in partnership with “Tomita,” a shop that boasts immense popularity among Japanese ramen fans. Designed for the upcoming warmer season, it is a luxurious dish that allows you to enjoy the popular “Pork Ramen” style (a voluminous and rich ramen category) in a refreshing chilled format.
Shocking Volume! Basic Info on the Tomita-Supervised “Chilled Pork Mazemen”
First, let’s look at the details of this high-impact new product.
- Product Name: Chukashoba Tomita Supervised: Chilled Pork Mazemen
- Price: 680 yen ($4.50 USD) (734.40 yen ($4.85 USD) including tax)
- Release Date: Rolling release starting Tuesday, April 14
- Sales Area: 7-Eleven stores across Japan (excluding some regions)
A major draw is that because it is being rolled out at stores nationwide, fans across Japan can experience Tomita’s dedication to quality. Despite the affordable price point typical of a convenience store (Konbini)—sitting in the low 700-yen range including tax—the contents are incredibly hearty and satisfying.
Firm & Chewy! An Extraordinary Dedication to Noodles
The most noteworthy point of this “Chilled Pork Mazemen” is the texture of the noodles.
Recreating the signature “Gokubuto” (extra-thick) noodles (approx. 0.15–0.2 inches thick) of Tomita, this dish achieves a balance between a “Washi-washi” (strong, firm bite) and “Mochi-mochi” (elastic softness) texture. Chilling the noodles enhances their firmness, giving them a presence that stands up to the rich soup. The aroma of wheat that fills your mouth is truly professional-grade quality.
Rich Tonkotsu Soy Sauce Soup with an Explosive Garlic Punch
The key to the flavor lies in the concentrated richness of the pork-based soup.
Deeply savory “Tonkotsu” (broth extracted from pork bones) is combined with sharp soy sauce and infused with an intense garlic aroma. Despite being a cold noodle dish, a powerful flavor spreads from the very first bite, keeping you engaged until the very end. It is an energetic soup perfect for when you want to boost your stamina during the hot Japanese summer.
Pure “Guilty Pleasure”! Luxurious Toppings for a Changing Flavor Profile
Another impressive feat of this product is the variety of ingredients included.
The lineup is so luxurious it could be called “all-the-fixings,” allowing for “Ajiben” (changing the flavor as you eat) by mixing them together.
- Diced chashu (seasoned pork blocks)
- Plenty of vegetables
- “Shrimp-flavored mayo” with added shrimp oil
- “Spicy onions” sautéed with chili oil and red pepper
- Minced garlic
- Bonito powder
- Black pepper
By mixing these all at once, you can enjoy a different flavor in every bite. The moment the mellow shrimp mayo meets the stimulating spicy onions is when you feel a true sense of “Haitokukan”—that “guilty pleasure” of something high-calorie yet irresistibly delicious.
From Matsudo to the World! The Philosophy of “Chukashoba Tomita”
“Chukashoba Tomita,” the supervisor of this dish, is one of Japan’s premier ramen establishments.
Representative Osamu Tomita operates under the philosophy of “providing an irreplaceable moment to customers around the world through food,” continuing to craft bowls of ramen without compromising on even the smallest detail. In Matsudo City, Chiba Prefecture (one of Japan’s ramen meccas), Mr. Tomita still stands in the kitchen himself to cook at the main shop.
That dedication is evident in their ultra-rich pork and seafood (Gyokai) soup, simmered for over 20 hours, and their homemade noodles made from carefully selected domestic wheat. The business has grown significantly, with 20 locations as of the end of February 2026, including international branches in countries like Thailand and Vietnam.
This philosophy has been inherited in the joint development with 7-Eleven. It is a confident creation that underwent repeated fine-tuning to select ingredients that remain delicious when cold and to balance both satisfaction and that “guilty pleasure” factor.
