How to Use the Tokyo Subway Without Getting Lost

Tokyo's rail map looks intimidating because it technically is three separate systems layered on top of each other — JR, Tokyo Metro, and Toei Subway — each run by a different company. The good news: one IC card taps through all of them, and once you understand that one fact, the rest is just reading a map.

One tap in, one tap out — the IC card system is the same gate, whichever of the three networks you're riding.

Quick facts

• One IC card (Suica or Pasmo) works on JR, Tokyo Metro, Toei, buses, and even konbini purchases.
• Welcome Suica is the tourist version: no deposit, valid 28 days, but the leftover balance is non-refundable — spend it down before you leave.
• Tap at every gate, including when transferring between different companies' lines.
• JR ↔ Metro/Toei transfers have no fare discount — they're treated as two separate trips. Metro ↔ Toei transfers get a ¥70 discount if completed within 60 minutes at a designated transfer gate.
• The last trains run around midnight to 1 AM — after that, it's a taxi or waiting until the first trains resume around 5 AM.

Three Companies, One Card

The three systems that make up "the Tokyo subway" in casual conversation are:

• JR (Japan Rail) — includes the Yamanote Line loop that circles central Tokyo, plus other lines.
• Tokyo Metro — 9 lines, color-coded, covers most of central Tokyo (Ginza, Marunouchi, Hibiya lines etc.).
• Toei Subway — 4 lines run by the city government, filling in gaps Metro doesn't cover.

They're separate companies with separate fares, but your IC card works on all three plus buses — you never need a different card or ticket type switching between them. For the bigger picture beyond Tokyo (Shinkansen, regional trains), see our guide to getting around Japan.

Getting an IC Card: Suica, Pasmo, or Welcome Suica

• Regular Suica or Pasmo: a ¥500 refundable deposit, no expiry if used within 10 years, refundable balance when you leave.
• Welcome Suica: designed for short-term visitors — no deposit, but it expires 28 days after purchase and any remaining balance cannot be refunded, so plan to spend it down (a vending machine drink or konbini snack works fine) before you fly home.
• All versions work identically at the gates — tap on, tap off, and the fare is deducted automatically based on distance.

Local tip: if your phone is an iPhone, you can add Suica directly to Apple Wallet and top it up with a credit card — no physical card, no running out of cash at a machine with a long line behind you.

How Transfers Actually Work

This is the part that trips people up. Your IC card doesn't care which company you're using — you tap in, ride, tap out, and the fare for that one trip is calculated. But switching companies mid-journey is its own transaction:

• JR to Metro (or Toei), or vice versa: no discount — you're charged as if you took two separate trips, even if you never left the station complex.
• Metro to Toei (or vice versa): a ¥70 transfer discount applies automatically, but only if you complete the transfer within 60 minutes and use a designated transfer gate (usually clearly marked at interchange stations).

In practice this means: check a route-planning app (Google Maps or Japan Transit Planner both handle this correctly) rather than trying to manually calculate fares — the app will route you efficiently and your IC card handles the actual charging.

Reading the Platform and Avoiding the Wrong Train

• Line colors and numbers are posted on every platform sign and inside the train — Tokyo Metro lines are color-coded (e.g., the Ginza Line is orange), which is often faster to spot than reading station names.
• Local vs. Rapid vs. Express trains run on the same JR lines but skip different stations — check the display above the platform or on the train itself before boarding if your stop isn't a major one.
• Platform numbers and door positions are marked on the ground at busy stations — lining up where your car's doors will stop helps in rush hour.

Local tip: if you're unsure which platform or exit to use, Tokyo Metro and JR stations post exit numbers tied to nearby landmarks (e.g., "Exit A3: Tokyo Tower") — matching that number to your map is often faster than guessing from a station name alone.

Rush Hour: What to Expect

Weekday rush hours (roughly 7:30–9:30 AM and 5:30–7:30 PM) are genuinely crowded — platform staff sometimes assist with boarding on the most packed lines. If you can, shift travel slightly outside these windows. Some lines run women-only cars during these hours, marked with pink signage on the platform.

FAQ

Do I need a separate ticket for JR vs. Metro vs. Toei? No — one IC card (Suica, Pasmo, or Welcome Suica) works across all three plus buses. You only need separate tickets for reserved Shinkansen seats.

What happens if my Welcome Suica still has balance when I leave? It's non-refundable, so spend it at a konbini or vending machine before departure.

Is there a discount for transferring between lines? Only between Tokyo Metro and Toei (¥70 off within 60 minutes at a transfer gate). JR transfers to/from Metro or Toei are charged as separate trips.

What time does the subway stop running? Last trains run roughly between midnight and 1 AM depending on the line; service resumes around 5 AM.

Can I use my phone instead of a physical card? Yes, on iPhone via Apple Wallet (Suica); Android support varies by model and region, so check compatibility before relying on it.
