Japan eSIM: install before departure and use data on your phone
Pocket WiFi: useful for sharing, but adds pickup, charging, and return
Local SIM card: may need an arrival counter and a physical SIM swap

When Japan eSIM is simpler

For solo travelers, couples, and travelers who want maps, translation, and messages on their own phone, eSIM avoids carrying another device or swapping a physical SIM.

When pocket WiFi may still fit

Pocket WiFi can help when several devices need one shared connection. Remember the tradeoffs: pickup, return, battery charging, device loss risk, and another item to carry.

When local SIM cards are less convenient

Local SIM cards can require a compatible phone, a physical SIM tray, arrival-time purchase, and manual setup. If your phone only has eSIM or you want to prepare early, Japan eSIM is often more convenient.
