Ramen has evolved from a simple Chinese noodle soup into one of Japan's most iconic culinary exports. In Hong Kong, the bowl's popularity has soared over the past decade, with specialist shops opening across every district from Causeway Bay to Tsim Sha Tsui. Understanding the four foundational styles, shoyu, miso, tonkotsu, and shio, is essential for anyone who wants to appreciate the depth and diversity of this dish. Each style represents a different approach to broth, seasoning, and regional tradition. This article examines each in detail: their historical roots, key ingredients, typical toppings, and the specific bowls you can find in Hong Kong today. For a broader overview of ramen in Hong Kong, check out our beginner's guide.

Ramen is not a single dish but a category with endless variations. The four core styles are defined primarily by their tare (seasoning base) and broth type. Shoyu uses soy sauce; miso uses fermented soybean paste; tonkotsu relies on pork bones boiled to creamy richness; and shio depends on salt and clear broth. Below we explore each style, drawing on widely known facts and real examples from Hong Kong's ramen scene. If you are new to ordering, our beginner's tips for ordering Japanese food can help you navigate the menu.

Shoyu Ramen: The Classic Soy-Sauce Base

Origins and History

Shoyu ramen is widely considered the oldest of the four major styles. It originated in the early 20th century in Tokyo, where street vendors began serving Chinese-style noodles in a broth seasoned with soy sauce. The first dedicated ramen shop in Japan, Rairaiken, opened in Asakusa in 1910 and served a shoyu-based soup. This style became the standard for what is now called Tokyo-style ramen. The broth is typically a blend of chicken, pork, and vegetables, simmered for several hours, then seasoned with a tare made from soy sauce, mirin, sake, and sometimes kombu (kelp) or dried fish. The result is a clear, brownish soup with a savoury, slightly sweet flavour that balances umami and acidity.

Key Characteristics

  • Broth: Clear, medium-bodied, often chicken-and-pork based, sometimes with seafood elements.
  • Tare: Soy sauce (shoyu) blended with mirin, sake, and sugar. Regional variations use different soy sauce types, koikuchi (dark) or usukuchi (light).
  • Noodles: Medium-thin, curly or straight, with a firm bite (often made with kansui, an alkaline mineral water).
  • Toppings: Chashu (braised pork belly), menma (fermented bamboo shoots), nori (dried seaweed), green onions, a soft-boiled ajitama (seasoned egg), and sometimes narutomaki (fish cake). For more on toppings, see our ramen toppings guide.

Regional Variations

While Tokyo-style shoyu is the best known, other regions have their own interpretations. Asahikawa ramen from Hokkaido uses a shoyu base but adds pork and fish broth, often topped with a layer of lard to keep it hot in winter. Wakayama ramen in western Japan uses a darker, more intense soy sauce and a tonkotsu-shoyu hybrid broth. In Hong Kong, most shoyu bowls follow the Tokyo template, but some shops offer Hakata-style or Wakayama-inspired versions.

Where to Try Shoyu Ramen in Hong Kong

Several ramen-ya in Hong Kong specialise in shoyu. Shukotsu Tori in Wan Chai (G/F, 18 Ship Street) serves a chicken-and-pork shoyu broth with a clear, elegant finish. Mashi No Mashi in Wan Chai (G/F, 29 Burrows Street) offers a wagyu-based shoyu ramen for HK$168. Ramen Jo in Causeway Bay (Shop 1, 11-13 Cleveland Street) serves a classic Tokyo-style shoyu with a rich, balanced tare. For a lighter option, Kikanbo (G/F, 25-27 Haiphong Road, Tsim Sha Tsui) offers a shoyu broth with a spicy kick. Prices range from HK$88 to HK$168 per bowl.

Miso Ramen: Fermented Soybean Richness

Origins and History

Miso ramen is a relatively recent invention, first appearing in Hokkaido in the 1960s. The style was popularised by Miso Kobo (now a chain) in Sapporo, where chefs added miso paste to a chicken-and-pork broth to create a hearty, warming soup suited to the cold northern climate. The fermentation process gives miso a complex, savoury-sweet flavour with notes of yeast, salt, and umami. Today, Sapporo is the undisputed capital of miso ramen, and the style has spread worldwide, including to Hong Kong.

Key Characteristics

  • Broth: Thick, rich, often cloudy from the miso paste. Base broth is typically chicken or pork, sometimes with added seafood or vegetables.
  • Tare: Miso (fermented soybean paste), common types include white miso (mild), red miso (stronger), and mixed miso. Often combined with garlic, ginger, and sesame.
  • Noodles: Medium-thick, wavy, and chewy to hold up to the dense broth.
  • Toppings: Chashu, corn (a signature Hokkaido addition), butter (another Hokkaido touch), bean sprouts, ground pork, green onions, and sometimes a pat of butter that melts into the soup.

Regional Variations

Sapporo-style miso ramen is the most common, but other regions have their own twists. Sendai miso ramen uses a lighter miso and often includes seafood. Edo-style miso ramen in Tokyo blends miso with a shoyu tare for a darker colour. In Hong Kong, most miso bowls follow the Sapporo template, with corn and butter as common toppings.
