Arai Yakushi-mae, Numabukuro, Saginomiya, Shimo-Igusa

When you step off the Seibu Shinjuku Line at these stations, you find yourself in a residential area so quiet it's hard to believe you're in Tokyo. But venture a little into the alleys near the station, and the signs of snack bars begin to light up, signaling the arrival of night.

This area centers around four stations—Arai Yakushi-mae, Numabukuro, Saginomiya, and Shimo-Igusa—each with a small drinking district within walking distance. In particular, the north exit of Numabukuro and the south exit of Saginomiya are known for clusters of snack bars and girls bars.

The nightlife here is dominated by snack bars and girls bars. Flashy venues like kyabakura (hostess bars) or host clubs are rare. Instead, the atmosphere is homey, with regulars chatting casually with the mama or staff. Prices are reasonable: at a snack bar, expect around 3,000–5,000 yen per hour including cover charge.

Girls bars are similarly affordable, often with just a drink fee, making them easy to enter even for first-timers. Concept cafes and lounges are almost nonexistent, so this area is for those who want to focus on drinking and conversation.

Access is easy: 15–20 minutes from Shinjuku on the Seibu Shinjuku Line. Last trains are relatively early, so starting around 8 PM is recommended. There are also chain izakayas and karaoke places near the stations for a second round.

A note of caution: many snack bars require reservations, so call or check social media before visiting. Also, since it's a residential area, keep noise down and enjoy quietly—that's the local rule.
