Japanese Tavern "Mata Aini Yukimasu" Nishi-Shinjuku at Go Shinjuku

Lively neo-izakaya near Seibu-Shinjuku with a Showa-retro vibe, oysters, sake sours and all-you-can-drink party courses.

Mata Aini Yukimasu is a lively neo-izakaya a short walk from both JR Shinjuku and Seibu-Shinjuku, with a Showa-retro interior and a menu that mixes classic izakaya staples with a few playful modern touches. The signature is fresh oysters from Ishinomaki, served raw on the half shell, plus a kettle of clams steamed in sake that doubles as both a dish and a small event at the table.\n\nThe drinks list is broad, with a focus on flavoured sake sours, plum and shiso versions in particular, alongside beer, shochu, wine and a steady rotation of seasonal cocktails. Course plans with all-you-can-drink start at a very accessible price point, which is why the room is popular with both after-work groups and weekend birthday parties.\n\nFor a Shinjuku night that wants a fun, easy-to-join atmosphere with reliable food and good sake-sour energy, Mata Aini is a confident pick. Book a course for groups of four or more.
