Tokyo's subway system carries approximately 14 million passengers daily, making it one of the world's busiest urban rail networks. This dual-system structure—comprising Tokyo Metro (9 lines) and Toei Subway (4 lines)—can be confusing for first-time visitors, but mastering a few key principles will allow you to navigate Tokyo's underground with ease.
Tokyo's subway uses a "distance-based fare" system, with ticket prices calculated based on travel distance—generally, the farther you go, the higher the cost. Base fares start at ¥190, with maximum fares around ¥320 (for trips over approximately 20 km). Tokyo Metro and Toei Subway operate separate ticket systems, so if you need to travel across both networks, you may need to purchase separate tickets from each company. Alternatively, using IC cards like Suica or PASMO for direct tap payments is highly recommended—this eliminates the hassle of waiting in line for tickets every time.
Tokyo Subway's Unique Operational Logic
The biggest difference between Tokyo's subway and other cities' systems lies in its management structure: Tokyo Metro is a private company while Toei Subway is operated by the Tokyo Metropolitan Government. Tokyo Metro operates nine lines including the Ginza, Marunouchi, Hibiya, Chiyoda, Yurakucho, Hanzomon, Nanboku, Tozai, and Tozai lines; while Toei Subway manages four lines: the Asakusa, Mita, Shinjuku, and Oedo lines. Although their ticket systems operate independently, both now accept the same IC cards at each other's stations—a major convenience for independent travelers.
It's worth noting that Tokyo's subway stations frequently have "duplicate" names. For example, "Shinjuku" appears for both Tokyo Metro's Shinjuku Line and JR's Odawara Line, but these are actually separate entrances. Similarly, "Shibuya" connects multiple rail lines including Tokyo Metro's Hanzomon Line, JR's Yamanote Line, and Tokyu's Den-en-toshi Line—the gate you exit from determines which line you can access, so don't simply head for the station based on the name alone. The best approach is to first memorize the "line name + color" you need to ride, such as "the red Marunouchi Line" or "the blue Tozai Line," and follow the color-coded signs within the station—this is more reliable than relying on Japanese characters alone.
Platform Facilities: What You Need to Know
Tokyo's subway platforms have improved significantly in recent years. Since 2019, all new stations on Tokyo Metro's Tozai Line have been equipped with Platform Screen Doors (PSDs), and other lines are gradually being retrofitted. If you encounter a platform without PSDs, please maintain a safe distance—especially during rush hours when crowds pushing toward arriving trains can be dangerous.
Most major transfer stations (such as Shinjuku, Ikebukuro, Shibuya, Ueno, Iidabashi, and Nihombashi) have clearly marked "connecting passages." However, these passages can sometimes be quite long. For example, walking from Tokyo Metro Marunouchi Line's Shinjuku Station to Toei Shinjuku Line takes approximately 5-7 minutes—this shouldn't be overlooked when planning your itinerary. Some large stations (such as Otemachi) are major hub intersections with multiple lines, and station navigation signs can be extremely complex. When making transfers for the first time, it's advisable to allow a 15-minute buffer.
Additionally, not all subway entrances in Tokyo have elevators. It's recommended to check in advance whether your destination station has wheelchair-accessible elevators, or prepare a card to ask station staff—they will typically escort you or direct you to the nearest elevator. This is one of Tokyo subway's thoughtful service features.
Women-Only Cars and Special Needs Services
Tokyo's subway implements a "women-only car" system during morning rush hours (7:30-9:30 AM). The last car (Car No. 10) on Tokyo Metro lines is typically designated as women-only, while Toei Subway varies by line. If you are a female passenger traveling during rush hours, this is the safest option; male passengers should avoid entering the last car during these periods to avoid violating regulations and causing misunderstandings.
Families with strollers should note that Tokyo's subway elevators are usually located near ticket gates rather than in the center of platforms. If you need to use a wheelchair or stroller, please use the "priority elevator"—never attempt to carry a stroller down stairs, as this is dangerous and may damage the equipment. Some quieter stations (such as Shin-kochi and Suitengumae with lower passenger flow) only have stairs and no elevators. When planning your itinerary, consider avoiding these stations or confirming accessibility facilities in advance.
Ticket Options and Money-Saving Strategies
If your itinerary involves extensive subway travel, a one-day pass is worth considering. Tokyo Metro's "Tokyo Metro 1 Day Pass" is priced at ¥600 (for continuous use), and Toei Subway offers a comparable day pass (¥700). However, if your trip covers both Tokyo Metro and Toei lines, the "Tokyo Subway Ticket" (a combined day pass) is recommended, priced at ¥800 and allowing unlimited rides on both companies' entire networks. This ticket is ideal for itineraries visiting more than 4-5 stations in a single day—cost-wise, it works out better than purchasing individual tickets.
Foreign visitors can also purchase the "Tokyo Subway Ticket" in 24, 48, and 72-hour versions, priced at ¥800, ¥1200, and ¥1600 respectively. These allow unlimited rides on Tokyo Metro and Toei Subway lines within the validity period, making them ideal for travelers staying in Tokyo for 2-3 days with intensive sightseeing plans. These tickets can be purchased at major tourist station ticket windows (English service available) by presenting your passport.
Operating Hours and Night Services
Tokyo's subway first trains depart around 5:00-5:30 AM, and last trains run around midnight to 12:30 AM, though schedules vary slightly by line. Some "holiday express" lines on Fridays and Saturdays have later final departures. If you're traveling at night, it's recommended to download the official "Tokyo Subway" app or check each line's timetable to avoid missing the last train. Late-night subway ridership drops significantly, but stations maintain basic lighting and remain safe.
Travel Tips
Tokyo's subway "fare adjustment machine" ( Fare adjustment machine) is an important facility that is often overlooked. If your IC card balance is insufficient and you don't have cash to purchase a single journey ticket, never attempt to rush through the gate—instead, tap your card at the fare adjustment machine. It will automatically calculate the difference and allow you to top up using credit card or electronic payment to exit the station. This is a recent feature that is very visitor-friendly.
One final reminder: Restrooms in Tokyo's subway stations are sparsely distributed—not every station has them. If you have facilities needs, it's advisable to use restrooms at major stations (Shinjuku, Shibuya, Ikebukuro, Ueno, Tokyo, Nihombashi, etc.) in advance. Some stations require obtaining a key from the service counter after entering. Keeping these details in mind will ensure a smoother Tokyo independent travel experience.
