Shinjuku Baby Care & Stroller Guide

Shinjuku is the world's busiest railway hub, serving over 3.5 million passengers daily. For visiting families with a stroller, the labyrinth of multi-level exits and crowds can feel overwhelming. The good news: directly connected to Shinjuku's main exits are some of Tokyo's most well-equipped department store baby care suites, with private nursing cubicles, boiling formula water dispensers, and diaper stations.

Verified against official department store and railway floor guides. Facility hours and equipment may change, so please check official signage on site.

Navigating Shinjuku Station with a Stroller

Shinjuku Station has dozens of underground tunnels and split-level platforms. To avoid getting stuck in stairs:

• Best Gate for Strollers: Use the New South Gate (Shin-Minami) or Miraina Tower Gate. These modern concourses have step-free elevator access directly to platforms, Takashimaya Times Square, and the express bus terminal (Busta Shinjuku).
• Subway Connections: Marunouchi Line, Fukutoshin Line, and Shinjuku Line are easiest to access with a stroller from the underground concourse leading to Isetan (Exit B2/B3 elevator).
• Avoid Rush Hours: Avoid moving strollers through Shinjuku Station between 07:45–09:15 and 17:30–19:00 on weekdays.
