Practical tips for Japan
- Load an IC transit card like Suica or Pasmo onto your smartphone wallet for seamless tap-and-go rides on nearly all subways, trains, and buses nationwide.
- While cards are increasingly accepted in cities, carry cash for traditional eateries, street food stalls, and temple admission fees.
- Wear slip-on shoes since you will frequently need to remove your footwear when entering temples, ryokans, and traditional restaurants.
