What Travelers Need to Know About Nakano’s New West-Side Connection
Scheduled to open at noon on December 6, 2026, the free route will cross the tracks between Nakano 3-chome and Nakano 4-chome beside the west ticket gate.
Nakano Station’s new west-side north–south passage and adjoining west ticket gate are scheduled to begin service at noon on Sunday, December 6, 2026. The pedestrian-only passage is planned to provide a free route across the tracks between Nakano 3-chome and Nakano 4-chome. This is still a future schedule, and surrounding plaza and pedestrian-deck construction is expected to continue afterward, according to the joint Nakano City announcement.
The short answer: scheduled to open at noon on December 6, 2026
Status reviewed September 18, 2026: The latest supplied official announcement, issued July 7, schedules service to begin at noon on Sunday, December 6, 2026. No later official reconfirmation was supplied, so this should not be read as confirmation that the passage is already open or as a guarantee against delays.
Nakano City, JR East, Tokyo Metro, and the Urban Renaissance Agency jointly announced the schedule on July 7, 2026.
The project centers on a pedestrian passage crossing above the railway tracks on the west side of Nakano Station. It is planned to measure approximately 80 meters long and 19 meters wide, with entrances named the New North Exit and New South Exit (Momozono Exit).
The passage is scheduled to open with the elevated station facilities and west ticket gate. It is one phase of a larger station-area project, however—not the completion of every adjoining plaza, deck, or outdoor approach.
If you plan to use the new entrance on or shortly after December 6, check a current Nakano City, JR East, or Tokyo Metro notice before traveling.
Where the passage goes and how travelers will use it
The west-side passage is planned to cross the railway between Nakano 3-chome on the south side and Nakano 4-chome on the north side.
Passengers taking a train will instead use the adjoining west ticket gate. Housing Japan’s project reporting places that gate on the second floor of the elevated station building. After passing through it, passengers should follow current signs for the appropriate JR or Tokyo Metro platform.
| What you are doing | Where to go |
|---|---|
| Crossing north to south | Remain in the free north–south passage; do not enter the ticket gate |
| Taking a train | Use the west ticket gate, then follow signs for your platform |
For now, treat the new exit names as station-navigation points rather than landmark directions. The supplied project information does not establish their precise walking positions relative to Nakano Broadway, Sun Mall, or Nakano Shikinomori Park, so exact landmark routes would be premature.
This project is at Nakano Station, which serves JR Chuo rapid, JR Chuo-Sobu local, and Tokyo Metro Tozai services. It is not at Shin-Nakano Station.
Planned elevators, escalators, and passenger facilities
The project plan includes four elevators, each with a stated capacity of 15 people, plus accessible restrooms and a baby-care room, according to the JR East project overview published through PR Times.
Housing Japan’s secondary project reporting also describes 15-person elevators and both upward and downward escalators connecting the new concourse with the platforms.
Because the facilities have not yet opened in the supplied evidence, treat them as planned provision. Do not assume that every elevator, escalator, restroom, or platform route will be operational from the first minute of service. Travelers relying on step-free access should check current JR East or Tokyo Metro accessibility notices shortly before traveling.
What opens in December—and what comes later
December 6 marks the scheduled start of a new station phase, not the completion of the entire redevelopment around Nakano Station.
| Milestone | Scheduled timing | Status |
|---|---|---|
| North–south passage, elevated station facilities, west ticket gate, and associated west-side elements | Noon, December 6, 2026 | Announced start of service |
| Atre Nakano | December 9, 2026 | Separately reported retail opening |
| South station plaza | Fiscal year 2028 | Target |
| Full new north station plaza | Fiscal year 2029 | Target |
Atre Nakano is separately reported to be scheduled to open on December 9, 2026, three days after the station facilities. A precise tenant count should not be treated as settled because it is not confirmed in the supplied primary project evidence.
The later plaza targets come from the joint municipal announcement: the south station plaza is planned for fiscal year 2028, while the full new north station plaza is planned for fiscal year 2029. Pedestrian decks and surrounding approaches are also expected to be developed in stages.
An open passage would not mean every adjoining deck, plaza, retail area, or outdoor approach is complete.
What to check before using the new entrance
Shortly before traveling:
- Reconfirm the opening notice. Check Nakano City, JR East, or Tokyo Metro for any schedule change.
- Follow current station signs. On-site signs and temporary directions should take priority over older online maps.
- Allow extra time. Construction around the entrances may create temporary turns or diversions that do not appear immediately in map apps.
- Ask station staff when necessary. Do this if the west-gate route to your platform is unclear or if you require step-free access.
Several practical details remain unresolved in the supplied evidence: the passage’s operating hours, overnight access, precise entrance positions relative to nearby landmarks, bicycle rules, post-opening construction diversions, and whether every planned passenger facility will operate from day one.
Everyday effects can only be assessed after pedestrians and passengers begin using the route.
The passage is also intended to provide an additional evacuation route from south of the Chuo Line toward the Nakano City Office area during an emergency. For post-opening conditions—including operating hours, facility availability, platform routes, and construction diversions—use current municipal, railway-operator, and station notices rather than pre-opening descriptions.
Is this new passage at Nakano Station or Shin-Nakano Station?
It is at Nakano Station, served by the JR Chuo rapid, JR Chuo-Sobu local, and Tokyo Metro Tozai lines. Shin-Nakano is a separate Tokyo Metro station and is not part of this project.
Nakano Station’s free west-side north–south passage and new ticket gate are scheduled to open at noon on December 6, 2026, creating a cross-track connection between Nakano 3-chome and Nakano 4-chome. Recheck the schedule before traveling, and expect surrounding plaza and pedestrian-deck work to continue in later phases.
