soba MAREN Shibuya: A Mazesoba Worth Going Out of Your Way For

soba MAREN in Shibuya is one of those mazesoba spots that reminds you how much range the ramen style actually has. The shop traces back to Osaka, born out of a former Japanese cuisine chef’s approach to the format.

This means nothing feels thrown together. It landed in Shibuya and has been drawing lines ever since. The space is tight — eight seats, mostly counter — and ordering is via ticket machine outside (cashless only, English available).

Shoyu Mazesoba

This is the one I keep coming back to. The tare is built from four types of soy sauce, including one brewed in traditional wooden barrels, with oyster umami folded in as a hidden layer. That’s mixed with chicken oil rendered from domestic chicken. The result is shoyu-buttery and deeply savory — rich without being heavy.

The noodles are thick and chewy, made in-house from domestic wheat blended with whole grain flour, and they arrive already coated in the tare. First bite, you get that al-dente snap, then the shoyu and oil start doing their thing as you chew.

Toppings are well-considered: two types of low-temperature chashu — small rare pieces and thin slices draped over the side — plus a high-grade egg yolk, bamboo shoot tips, and raw onion to cut through the richness.

The table has five condiments: niboshi vinegar, spicy miso, soy tare, ichimi chili, and black pepper. My move is to eat the first half relatively pure, then crack the egg yolk, mix everything together, and add niboshi vinegar for a brightness shift.

At the end, drop your complimentary rice into the remaining tare. It’s the right way to finish.

Shio Mazesoba

The shio is interesting, and if you’re going lighter that day, it’s worth your time. The salt tare uses mosio — a seaweed salt that carries natural ocean umami — blended with kombu and bonito, then layered with the same chicken oil as the shoyu version.

The move that sets it apart is a ball of shredded chicken mixed with Kyoto shibazuke — a traditional pickled vegetable with a distinct purple color and tangy bite. It sits in the center of the bowl and looks almost decorative until you break it up and mix it in.

That’s when things get interesting: the acidity from the shibazuke shifts the whole flavor profile, and paired with the shiso oil, it goes somewhere unexpectedly bright.

A lemon wedge comes on the side for the back half of the bowl. Use it. The shio is more delicate than the shoyu, but the shibazuke element alone makes it unlike any mazesoba I’ve had elsewhere. My personal preference is still the shoyu, but the shio is the more surprising bowl.

Seasonal Specials

soba MAREN rotates limited-time bowls that lean into premium ingredients, and if one is on the board when you visit, it’s worth taking seriously. I had a truffle mazesoba with wagyu beef slices that was genuinely excellent — the kind of bowl where the luxury elements actually justify the price rather than just padding it.

The truffle fragrance hit immediately on the way to the table. The wagyu slices were draped over the noodles and melted into the tare as you mixed. It’s on the higher end, but it’s not a gimmick. Keep an eye on their Instagram for what’s running.
