Sakura Season: Japan's Peak Travel Period
Late March to mid-April is when Japan's cherry blossoms bloom — and when 90% of travel articles tell you to visit. The trees are stunning, but so are the crowds. Reliable data connection becomes essential for navigating packed trains, finding less-crowded spots, and checking real-time bloom forecasts.

Sakura Season eSIM Tips
1. Buy early. Sakura season = peak demand. Buy and install your eSIM 2-3 days before departure.
2. Get more data than usual. You'll take more photos, use maps more, and post to social media more. Add 1-2 GB to your normal estimate.
3. Download bloom tracking apps: Weathernews Sakura Ch, tenki.jp — both need data.
4. Hotel WiFi will be slow. Peak season means full hotels = overloaded WiFi. Your eSIM is your reliable backup.
