A Japan trip lives or dies on whether you sorted out cash + a Wise card + an eSIM + the right gear before you flew. The alternative — losing ¥4,000 at an airport exchange counter, finding the hotel Wi-Fi can't load Google Maps, then shivering through a busy district at night hunting for an ATM — is exactly the kind of arrival day this list helps you avoid. Works for solo travel from 4 to 14 days, with a template and product links built in.

5 things to absolutely do before you leave

1. Issue a Wise / Revolut card and fund it

• Apply 2 weeks before departure (physical cards ship in 1-2 weeks)
• Top up $1,500-$3,000 equivalent by the time you fly

2. Buy your eSIM and install 24 hours before departure

• Airalo Japan eSIM: about ¥1,500 for a 5GB week
• Holafly Japan: about ¥5,000-¥10,000 for the unlimited plan
• Details: #111 SIM / eSIM / pocket WiFi compared

3. Book hotels and pay by card

4. Pre-book your high-ticket activities
