Quick guide: why pick an eSIM Japan unlimited 15 days
For a roughly two‑week stay in Japan, an "eSIM Japan unlimited 15 days" removes data worries when you rely on maps, travel apps, online bookings and frequent social sharing. Many Japan plans offer 5G/4G LTE, unlimited hotspot and instant QR code delivery — useful for families who want to tether a tablet or for anyone doing heavy navigation or live uploads.
What to check before you buy
- Network coverage: carriers like NTT Docomo, au (KDDI), SoftBank and Rakuten cover most tourist routes.
- Hotspot policy: choose plans explicitly listing "Unlimited Hotspot" if you need tethering.
- Activation window: look for plans that let you activate within 180 days for flexibility.
