What is the best eSIM for Japan sakura season?

The best eSIM for a Japan cherry blossom trip is one that connects you to top local networks, offers enough high-speed data for navigation, translation, and sharing photos, and lets you activate on arrival. For a 7–10 day sakura itinerary in Tokyo, Kyoto, and Osaka, a 5–10 GB Japan eSIM is usually ideal for typical usage. Look for clear information on supported networks, when validity starts (usually on first connection in Japan), and whether you can top up online if you run out of data during your trip.
