Use a digital IC card: You can add a Suica or Pasmo card to your smartphone wallet app, which lets you tap and pay for trains, buses, and some shops without carrying the physical card.
Carry cash: While cards are widely accepted, some smaller shops, restaurants, and rural areas may only accept cash. Carrying a reasonable amount of yen is helpful.
Bring a coin purse: Coins are common for small purchases, lockers, vending machines, and temple offerings, so a coin purse keeps them organized.
Pack lightly or use an extra suitcase: If you plan to stay overnight or buy souvenirs, having an extra small suitcase or backpack makes travel easier. Many trains have limited luggage space, so compact packing is best.
Dress in layers: Hakone’s weather can change quickly in the mountains, so layers help you stay comfortable during sightseeing.
Plan transport ahead: Use the Hakone Free Pass or check train and bus schedules in advance to maximize sightseeing time.
