If you’re exploring Japan and want to try a true hidden gem, Kokoro‑ya in Kusatsu is a must-visit for ramen lovers. This local ramen shop specializes in Yokohama Iekei Ramen, a style famous for its thick noodles and rich pork-and-soy broth.
Why is Kokoro‑ya so special? It brings authentic Iekei flavors from Yokohama to the Kansai region—something rare outside the Tokyo area. Instead of toning down the flavor, they go all in with deep, creamy broth, perfectly chewy noodles, and all the traditional toppings.
For example, their standard ramen bowl comes topped with tender chashu pork, spinach, seaweed, and even a soft-boiled quail egg—all classic components of real Iekei ramen. The soup is slow-cooked for hours to achieve that signature cloudy, savory richness.
In short, Kokoro‑ya delivers a bowl of ramen that’s rich, hearty, and unforgettable—just like the best shops in Yokohama.
A Menu That Speaks to Every Ramen Lover
Signature Soy‑Pork Broth & Salt‑Pork Broth Variants
Kokoro‑ya offers two excellent broth options: a soy-based pork broth (shoyu tonkotsu) and a salt-based pork broth (shio tonkotsu). Both are thick, creamy, and made from pork bones simmered for hours.
Why the choice? Some people love the deeper flavor of soy, while others prefer a lighter salt base. Either way, the rich soup coats the noodles beautifully, giving you that satisfying Iekei mouthfeel.
For example, the shoyu broth has a bold, smoky undertone, while the shio version feels cleaner but still hearty. Both are delicious—and both are 100% Iekei.
Max Ramen: Fully Loaded with Toppings Like Seaweed & Quail Egg
For those with a big appetite, the MAX Ramen is a must. It’s packed with double seaweed, extra chashu pork, spinach, and a creamy quail egg. The portions are generous, and the toppings balance out the rich broth beautifully.
It’s not just a meal—it’s an experience.
