• Use rechargeable IC transportation cards such as Suica, PASMO, or ICOCA where available for convenient train, subway, bus, and everyday payments.
• Japan has an extensive public transportation network, so trains and metro systems are often more convenient than renting a car in major cities.
• Carry some Japanese yen, especially when visiting smaller restaurants, temples, rural areas, and traditional establishments where card payments may not always be available.
• Avoid talking loudly on trains and follow local etiquette regarding queues, waste disposal, temples, and public spaces.
