Menya Kaijin Shinjuku: A Clear Shio Ramen Experience from Daily-Varying Fish Bone Broth

🍜A Unique Shio Ramen Made from Fish Heads and Bones

Menya Kaijin (めんやかいじん) is a specialty shop that serves shio ramen with broth simmered from ara (fish heads, bones, and collars — the most flavorful parts of the fish). In a ramen culture dominated by rich tonkotsu (pork bone) and shoyu (soy sauce) broths, their style, centered on a clear seafood broth, is quite rare in Tokyo. This renowned establishment has even been selected as one of Japan's Top 100 Ramen Shops in the past.

The greatest characteristic of this shop is that the ara (fish heads and bones) used for the broth changes daily. Written in brushstrokes on the shop's wall is 'Today's Ara,' listing 4-5 types of fish such as sea bream (madai), splendid alfonsino (kinmedai), yellowtail (buri), conger eel (anago), and amberjack (hamachi), depending on the day. Since the combination changes according to what's sourced, encountering slightly different flavored broths with each visit has become a connoisseur's delight.

Ren

Ara refers to the heads, bones, and surrounding parts of fish. When simmered instead of discarded, they create an elegant broth with more concentrated umami than the flesh itself. This is a technique traditionally used in Japanese cuisine, and Kaijin's style applies it to ramen.

🚶How to Get There — 1 Minute from the Station, But Hard to Spot

Access is excellent; simply exit JR Shinjuku Station's Southeast Exit and head straight towards the station rotary. You'll arrive in just a few dozen meters. However, there's no ramen shop-like sign on the first floor, only a small, vertical 'Menya Kaijin' sign at the entrance of a multi-tenant building. First-time visitors might walk past it, so please look carefully for the building's entrance.

🏠Shop Atmosphere — A Calm, Bar-like Space

As you open the door, you're greeted by a tranquil atmosphere unlike a typical ramen shop. The lighting is somewhat dim, pop music plays in the background, and the wooden interior contributes to a bar-like ambiance. With 6 counter seats, two 4-person tables, and one 2-person table, it's not overly spacious, but it doesn't feel cramped, allowing you to enjoy your meal at a relaxed pace.

The clientele is relatively young, mainly Japanese with a sprinkling of foreign visitors. The gender ratio is fairly even, with both solo diners and couples present. Tissues are neatly placed at the end of tables, and chopsticks are self-serve. There's space under the tables for bags, so a backpack can fit without issue.

Due to its location in Shinjuku, an area lively even late at night, Kaijin offers an elegant space with subdued lighting where male customers don't appear intimidating. It lacks the typical ramen shop tension of 'packed counters and mostly male diners,' making it a **rare and valuable spot in Shinjuku for female solo travelers, with a low psychological barrier to entry.** It's especially recommended for those who want to enjoy a quiet meal alone in the evening.

Mei

Ramen shops with a bar-like atmosphere are surprisingly rare, which is a great plus for dates or dinner with colleagues. Solo diners and couples alike will feel comfortable, making it a convenient option for an evening meal in Shinjuku.

📝How to Order — Verbal Ordering, English Menu Available

Kaijin does not use a ticket machine. Once seated, you order verbally to the staff at the counter. While the Japanese handwritten menu (with photos) is usually on the table, a separate English menu is available, which you can request by saying 'English menu, please.' You can also order by pointing to photos on the Japanese menu. Please remember that payment is cash or PayPay only (credit cards and transit IC cards are not accepted), so it's best to confirm you have cash before ordering.

1. Check for available seats at the 2nd-floor entrance and follow staff's guidance to your seat
2. Open the menu book. Ara-daki Shio Ramen is the signature dish.
3. Call a staff member across the counter and order by pointing. If you want a large portion (omori), tell them verbally here (it's free).
4. Water and chopsticks are self-serve. Condiments and water pitchers are provided on the upper counter.
5. Service from order to delivery is relatively quick (our ramen arrived 4 minutes after ordering during our visit).

The menu also includes Ara-daki Kōshio Ramen (あら炊き幸塩らぁめん), which has added spiciness, adjustable from mild (ほんのり / subtle) to ★★★★★ (maximum). Kōshio is recommended for spice lovers, while the regular shio ramen is best for those who want to savor the delicate saltiness. For a first visit, starting with the regular shio ramen combined with the Heshiko grilled rice ball set is a great way to experience the shop's unique character.

🎣'Today's Ara' — The Daily Changing Star

The true delight of Kaijin begins with checking 'Today's Ara' posted inside the shop. Written in bold brushstrokes on the wall are the names of the fish whose ara are being used that day. On our visit on April 17, 2026, the daily lineup included splendid alfonsino (kinmedai), yellowtail (buri), conger eel (anago), and sea bream (madai). Since the combination changes daily — sometimes featuring sea bream family fish, blue fish, white fish, Japanese amberjack (amadai), or amberjack (hamachi) — regulars look forward to 'today's lineup' with each visit.

If you visit multiple times, it's interesting to keep a record of 'Today's Ara' for each visit. The soup's character changes with each lineup – some days feature mainly white fish, others include blue fish, and some even have premium splendid alfonsino. Many regulars post about it on social media!

🔥Our Meal — Ara-daki Shio Ramen with Heshiko Grilled Rice Ball (Large Portion)

Soup — Light and Smooth, Yet Packed with Fish Umami

The first impression is a 'clear, serene salt flavor.' It's light and smooth with almost no oil, a mouthfeel that's the complete opposite of heavy tonkotsu broths. However, it's far from lacking; the umami and aroma of seafood are layered throughout the soup, deepening with every sip. It's delicate yet never becomes bland, a perfectly crafted bowl that you can drink entirely.

This direction is particularly perfect for those tired of rich, oily broths, or those looking for a light bowl of ramen to finish off an evening of drinking.

Noodles — Thin Straight Noodles with Wheat Aroma

The noodles are thin and straight, with a slight chewiness. They slide down smoothly, and when bitten, release a gentle aroma of wheat. They are designed not to overpower the delicate soup, striking a perfect balance. Even with a large portion, the quantity doesn't feel heavy, allowing you to enjoy it rhythmically to the very end.

Chicken Tsukune (Meatball) & Shrimp Tsumire (Dumpling) — A Red and White Contrast with Distinct Roles

The main toppings are the white chicken tsukune (meatball) and the pale pink shrimp tsumire (dumpling). In place of chashu (sliced pork), these two serve as both protein sources and provide flavor variations. The chicken tsukune is juicy and rich in flavor, offering a relatively distinct taste within the ramen. The shrimp tsumire has a strong shrimp flavor, naturally blending with the seafood dashi salt soup. You won't feel any lack without chashu.

Ginger & Shiso — A Mid-Course Accelerator for the Latter Half

Thin strips of ginger and shredded shiso (perilla leaf) are delicately placed on top of the bowl. The ginger provides a pungent kick, and the shiso a refreshing aroma. Since these strong flavors suddenly appear within the delicate soup, it's recommended not to mix them in from the start. Instead, eat about half of the ramen first, then gradually break them in. This adds layers of flavor as you progress, effectively preventing the dish from becoming monotonous.

Heshiko Grilled Rice Ball — A Side Dish Designed for 'Two-Stage Enjoyment'

Heshiko (mackerel fermented in rice bran for several months — a traditional specialty of Fukui Prefecture) is one of Japan's representative fermented foods, characterized by a deep, rich umami similar to miso or aged cheese. Kaijin's grilled rice ball is made by forming this heshiko with rice and then grilling it, offering a unique flavor where the umami of fermentation and the fragrant char of grilling are integrated.

The Heshiko grilled rice ball, served on a separate plate, is designed to be eaten in Kaijin's unique style. First, take a bite as is. The aroma of toasted rice, the fragrant char, and the umami of the fermented mackerel spread in your mouth. Then, when only a little is left, soak the rice ball generously in the soup, lightly break it apart, and enjoy. The fragrant rice and soup intertwine, revealing a new dimension to the ramen. This 'two-stage eating method' is clearly stated on the menu.

Mei

With its clear soup, red and white tsukune, and accents of myoga (Japanese ginger) and chili threads, this bowl is simply beautiful to look at. It's perfectly Instagrammable, but if you're taking photos, the first five seconds before the soup fogs up with steam are crucial. I recommend having your smartphone ready as soon as you sit down!

Large Portion (Omori) — As a Guideline Only

This time, we ordered the large portion with a rice ball, which was just the right satisfying amount for the average-sized male writer. While individual differences exist based on physique and eating habits, as a reference, those who eat a lot may feel more satisfied with a large portion, while women or those with smaller appetites often find a regular portion with a rice ball to be ample. Due to the thin straight noodles, even a large portion doesn't feel heavy, and the ramen is designed to be easy to finish, soup and all.
