Why you should experience Sangenjaya Izakaya Comaru in Tokyo, Japan.
Sangenjaya Izakaya Comaru is a compact standing bar where Taishido's neighborhood character, Japanese small plates, sake and a communal oval counter turn drinking into one of the most social experiences in western Tokyo.
Set along Chazawa-dori near Taishido Chuo Shopping Street and just steps from Taishido Hachiman Shrine, Sangenjaya Izakaya Comaru centers its entire room on an oversized counter built as a continuous loop, placing strangers, regulars and staff within immediate reach of one another. The format came directly from 2TAPS' founding interest in connecting people through restaurants, with the circle itself carrying the “maru” idea shared across the company's names. A June 2026 renovation retained that counter while replacing the brighter original finishes with solid tamo wood, muted ceramic tile, dark gray walls and curved pendant lighting, giving the nine-year-old bar a more mature physical character. The result is a tightly composed Taishido drinking room whose architecture gives 2TAPS' founding philosophy a physical shape.
What you should know about Sangenjaya Izakaya Comaru.
Sangenjaya Izakaya Comaru is best known for extending Ryo Kawachi and Naoya Koshiba's original Sangenjaya restaurant project into a standing bar built specifically around human connection, opening on November 9, 2018 as the third restaurant in the group that became 2TAPS. Kawachi and Koshiba had begun with Sancha Nomiba Marco in December 2014, conceiving their first restaurant around the idea of creating a drinking place where people could meet one another, before New Marco followed in September 2017 and Comaru pushed that principle into a smaller standing format. 2TAPS itself was incorporated on February 10, 2017 with Kawachi as representative director and Koshiba as director, and its name joined “two” with the act of tapping someone on the shoulder, another reference to the personal connections the founders wanted their restaurants to produce. Comaru translated that philosophy into architecture through its immense oval counter, deliberately placing drinkers around a shared surface where interaction could travel across the room. The company continued expanding through Shokudo Kado, Shimokita Rokkaku and Toranomon Rakki while keeping Comaru in Taishido, then closed the bar from May 18 through May 31, 2026 for its most substantial physical revision since opening. Comaru reopened June 1 under a new culinary direction centered on seasonal taishu kappo, with the original counter rebuilt in tamo wood and a new program of small plates and simmered dishes, carrying Kawachi and Koshiba's 2014 idea into another stage without removing the object that had defined the bar from its first night.
The 2026 kitchen places doteni skewers at the center of the revised menu, simmering ingredients in a miso-based preparation that gives the standing-bar format the depth of longer-cooked Japanese food. Small plates rotate with the season, while a large oden pot becomes a focal point during winter and extends the kitchen toward daikon, eggs and other ingredients slowly absorbing broth before service. Japanese sake arrives from breweries across the country, connecting those simmered preparations with a drinks program that has remained central to Comaru since its opening years. The counter completes the meal as much as the cooking does, keeping plates compact enough to share across the oval and preserving the social mechanics that Kawachi and Koshiba built into Comaru from the beginning.
How to fold Sangenjaya Izakaya Comaru into your trip.
Sangenjaya Izakaya Comaru works as the drinking stop within an afternoon tracing Taishido through an ancient shrine precinct, a century-old tramway and the tower that gave modern Sangenjaya its cultural center.
Begin at Taishido Hachiman Shrine, whose history reaches to the eleventh century through a tradition connecting Minamoto no Yoriyoshi and Yoshiie with prayers here before the Former Nine Years' War; Ensenji records place the construction of a formal Hachiman shrine during the Bunroku era of 1592 to 1596, and the precinct escaped wartime bombing before later earthquake reinforcement. Continue to Setagaya Line, whose first section opened from Sangenjaya to Setagaya on January 18, 1925 and reached Shimo-Takaido on May 1, preserving the surviving branch of the former Tamagawa Electric Railway after the main Tamagawa Line disappeared in 1969. Conclude at Carrot Tower, completed in 1996 with a name selected from a public competition proposed by a local middle-school student, and rise to its 26th-floor observation level above a complex containing Setagaya Public Theatre and Theatre Tram. The progression moves from Taishido's medieval religious history through the railway that accelerated suburban growth into the cultural tower of modern Sangenjaya before Sangenjaya Izakaya Comaru closes the route around the oval counter where Kawachi and Koshiba built their own version of neighborhood connection.
