Best eSIM Plans for Long Stays in Japan (14-30+ Days)

Quick Guide: eSIM for Extended Stays

Spending 2-4 weeks in Japan? Daily cost matters more than total price. A $19 plan for 30 days beats two $12 weekly plans. Look for providers with top-up support (Airalo, Ubigi) so you can add data without buying a new eSIM. For month-long stays: start with 10 GB. If you're working remotely or streaming daily, go unlimited. Ubigi's 30-day plans on NTT Docomo offer the best coverage for exploring beyond major cities.
