What Happened: Current Status Details
According to the official notice published on May 9, 2026, at 04:47 UTC, the Namboku Line service information page does not report any ongoing service suspensions (unten men'ai) or significant delays (chien). The page's structure, which typically displays such alerts prominently, shows no active incident at this timestamp.
The "Operational History" section of the source page archives past disruptions over the previous 35-day period. While the history log itself is not detailed in the source summary, its existence is a standard feature for travelers reviewing past reliability or seeking context for recurring issues.
Affected Services and Areas
Based on the absence of a disruption notice on the official source page, no specific sections of the Namboku Line are reported to be suspended or experiencing delays as of the publication time.
Namboku Line Through-Services
A critical aspect of the Namboku Line is its direct through-service operation with several private railways. This means trains run continuously across multiple company lines, creating a seamless journey for passengers. The official source page includes a section linking to the service status of these partner companies. Disruptions on any of these lines can directly impact Namboku Line operations.
The partner railways with through-service on the Namboku Line include:
- Tokyu Railways: Primarily the Tokyu Meguro Line.
- Saitama Rapid Railway: The Saitama Stadium Line.
For the most accurate picture of your journey, if you are traveling on sections that involve these railways, it is advisable to check both the Namboku Line page and the respective partner railway's service information.
What Travelers Should Do
The following advice is based solely on the standard procedures and information structure outlined in the official source.
- Check the Official Source Before Travel: Always verify the current status on the official Tokyo Metro Namboku Line page shortly before your departure. Status can change rapidly.
- Use the Visual Map: If the page indicates a disruption, consult the route map to understand exactly which stations and sections between Meguro and Akabane-Iwabuchi are affected.
- Review the History for Patterns: The 35-day history can help you anticipate if certain times of day or sections are prone to issues, though it does not predict future disruptions.
- Consider Alternative Routes: In the event of a major suspension, familiarize yourself with alternative subway lines (such as the Yamanote Line or Ginza Line) or JR East lines that serve similar corridors. Station staff can provide guidance during disruptions.
- Allow for Extra Time: Even minor delays can compound during peak hours. Building a buffer into your schedule is a prudent practice when relying on any urban rail system.

Frequently Asked Questions (FAQ)
1. How often is the Tokyo Metro service information page updated?
The official service information pages, like the one for the Namboku Line, are updated in real-time by Tokyo Metro's operations control center. Updates occur whenever there is a change in service status—such as the start of a delay, a suspension, or the restoration of normal service. There is no fixed schedule; updates are event-driven.
2. What does the "Operational History (Past 35 Days)" section show?
As indicated in the source page's structure, this section archives a log of service disruptions and informational updates for the Namboku Line over the previous 35 days. It allows travelers to review past incidents, though it does not provide detailed analyses or future predictions.
3. If the Namboku Line is delayed, will it affect other Tokyo Metro lines?
Not necessarily. Tokyo Metro lines largely operate independently. However, a major disruption on the Namboku Line could lead to increased crowding on parallel or connecting lines (like the Yurakucho Line or Marunouchi Line) as passengers seek alternatives. Disruptions are most likely to impact the private railways with which the Namboku Line has through-service (Tokyu and Saitama Rapid Railway).
4. Where can I find information about fares and schedules for the Namboku Line?
The service status page focuses exclusively on operational disruptions. For comprehensive fare tables, timetables, and route planners, you should consult the main Tokyo Metro website's "Fares & Tickets" and "Timetables" sections, or use a reputable third-party transit app that integrates official Tokyo Metro data.
Conclusion
As of the latest official update from Tokyo Metro, the Namboku Line is providing normal service across its entire route from Meguro to Akabane-Iwabuchi. The reliability of this information is grounded in the direct source from the rail operator.
For all your journeys on the Tokyo subway network, including the Namboku Line, the single most important habit is to check the official service status immediately before you leave. Bookmark the official page and make it part of your travel routine. This ensures you have the most accurate, up-to-the-minute information to plan a smooth journey through Tokyo.
