Getting Around
The Tokyo Metro and Toei subway networks, combined with the JR Yamanote Line loop, cover the city comprehensively and run to the minute on schedule. A Suica or Pasmo IC card loaded on a compatible phone functions as a single payment instrument for every train, bus, and subway line in the city, and also works at convenience stores and vending machines. The airport connections are among the best in the world — the Narita Express and Keikyu-Narita Express from Haneda both deliver to central Tokyo in under 40 minutes.
⚖️
Cash or Card
55% Cash, 45% Card. The major department stores, chain restaurants, and hotels are fully card-compatible, but the most memorable experiences in Tokyo — the standing ramen counter in Shinjuku, the tempura specialist in Asakusa, the jazz bar in Shimokitazawa — are frequently cash-only. Keeping 10,000–15,000 yen in physical notes as a daily baseline is the standard operating approach for navigating the city at its most interesting level.

Good to Know
The Koban — the small neighborhood police boxes found at major intersections throughout the city — are genuinely useful for directions and practical assistance, staffed 24 hours and operated by officers who know their specific neighborhood in granular detail. The unspoken rule of Tokyo transit is silence: phone calls on trains are considered impolite, conversations are conducted quietly, and the collective stillness of a full rush-hour carriage is one of the specific social experiences of the city that takes adjustment but becomes natural quickly.
🏧
ATMs
7-Bank ATMs inside any 7-Eleven are the gold standard for international card access in Tokyo — available at over 21,000 locations nationwide, 24 hours, English language interface, accepting Visa, Mastercard, American Express, and most international debit cards. Japan Post ATMs at post offices are the secondary option and have slightly more limited hours. Most convenience store ATMs charge a modest fee of 110–220 yen per transaction.
💳
Currency
Japanese Yen (JPY) is the currency. The notes are exceptionally well-designed and the denominations are clearly distinguishable — the 10,000 yen note (approximately $65 USD), 5,000, 1,000, and the functionally important 500 and 100 yen coins are all in constant daily use. Tipping is not practiced in Japan and attempting to tip can cause genuine confusion or polite refusal — the service is built into the price.
🔌
Plugs
Type A (two flat parallel pins, 100V, 50Hz in Tokyo and eastern Japan) — the same physical plug as North American outlets but at lower voltage. Modern electronics (phones, laptops, cameras) handle the voltage automatically and require no adapter for physical compatibility. A Type A adapter is needed for European and Australian plugs. High-wattage appliances designed for 220–240V should not be used without a step-up transformer.

Safety
Tokyo is consistently ranked among the safest major cities in the world and the practical experience matches the data — the city operates on a deep structural trust that extends to leaving bags unattended, losing wallets that are returned intact, and moving alone at any hour. The primary practical considerations are heat and humidity in July and August (temperatures above 35°C with humidity above 80% are common) and the earthquake preparedness protocols that are built into every building and public space.
✈️
Airports
Haneda International (HND) is the preferred gateway for most visitors — 15–30 minutes from central Tokyo via the Keikyu or Tokyo Monorail lines, with extensive international routes and a significantly more convenient arrival experience than Narita. Narita International (NRT) serves as the secondary hub with more low-cost carrier connections and a 60–90 minute transfer time to the city center via the Narita Express (N'EX) or Skyliner from Nippori.
