Hello, everyone. This is Sondo, the Store Manager of Kuro5.

After a wonderful evening savoring our juicy Fresh Harami and premium Wagyu tongue grilled over hot Binchotan charcoal, there comes a moment when almost every Yakiniku lover thinks, “I’d love to finish the meal with a warm, gentle soup.”

In fact, having a soup as a Yakiniku finale is highly beneficial for more than just warming your body. It cleanses the palate, washes away the meat’s rich oils, and elevates the entire dining experience to its absolute peak.
Today, I would like to share the profound dedication and scientific nutritional properties behind our signature “Rich Bone Broth” (Komtan Soup)—a dense, velvety soup where the entire soul of our domestic Wagyu is concentrated.
Squeezing Every Drop of Umami: High-Pressure and Long-Hour Brewing
Kuro5’s bone broth is completely different from ordinary soups that are simply boiled. It represents immense cooking hours and the absolute devotion of our culinary staff.
The stars of our preparation are selected domestic beef bones (Genkotsu) and chicken feet (Momiji), which are rich in dense gelatin. We place them generously into our special high-pressure deep pots, cooking them under intense pressure for hours until the bone fibers begin to dissolve.
This strict high-pressure extraction process forces the deep umami and rich gelatin locked deep inside the marrow to dissolve completely into the broth. The resulting soup is beautifully opaque, featuring a creamy, milky-white color and a remarkably smooth, velvety mouthfeel.

Only 0.3g of Sugars: Three Body-Restoring Merits of Kuro5 Bone Broth
Our bone broth is not only delicious but also functions as a natural elixir that restores your body. Here are three extraordinary merits verified by strict scientific analysis from the Food Environment Hygiene Research Institute:
- Extremely Low Sugars & Carbohydrates: It contains just 0.3g of sugars (0.7g of carbohydrates) per 100g. Guests on low-carb diets can enjoy this rich soup completely guilt-free.
- Superior Gut Health Support: The abundant amino acids like glycine and proline extracted from the bones gently protect and soothe your stomach lining, helping to restore optimal gut health.
- Rich Protein Boost for Recovery: With 5.5g of protein per 100g, it acts as a natural supplement that supports recovery after physical activity and boosts daily energy.
The Scientific Amino Acid Balance of Our Drinkable Elixir
The reason our soup is praised as a “drinkable skincare elixir” lies in its highly concentrated amino acids, which are the building blocks of collagen.

Our official analysis shows that every 100g of our broth contains 1,200mg of Glycine, 640mg of Proline, and 550mg of Glutamic Acid (the key to rich umami). These components are vital for maintaining skin elasticity and providing beauty support from the inside out.
With an energy value of just 110kcal and salt equivalent of only 0.107g per 100g, it is incredibly healthy, allowing you to drink every last drop without worrying about excess sodium.

Harmonizing Beautifully with the Fragrance of Our Binchotan Charcoal
At Kuro5, our trained staff provides a complete-attend service, grilling your Fresh Harami and Wagyu loin to perfect, golden-ratio doneness right before your eyes over Binchotan charcoal.

After enjoying the smoky, juicy meats, taking a warm sip of this white, dense bone broth brings an unparalleled sense of satisfaction and comfort. The transition from the powerful, savory grilled meat to the gentle, wrapping warmth of the soup amplifies the satisfaction of the entire meal.
This ultimate moment—where both your stomach and soul are filled with warm comfort—is the final piece of the “flawless Yakiniku experience” that Kuro5 promises to every guest.
A Perfect Warm Finale for Your Evening in Ikebukuro
Whether you want to refresh your body after a busy day or conclude a memorable dinner with someone special, let Kuro5’s bone broth serve as the ultimate warm finale.
The powerful energy of domestic beef bones concentrated in this single cup will support your body beautifully and deliciously.
