For short trips centred on maps and social apps, the per-GB plans from Airalo, Nomad and Ubigi are the best value. If you stream or tether a lot, unlimited plans (Holafly, Mobal, Sakura) are the safe choice. Ubigi runs on NTT docomo, Airalo on SoftBank.
Mobal's JP-number plans come with a Japanese 070/080/090 number with free incoming calls and SMS — handy for bookings and SMS verification. Japanese law requires an ID check, so they can't be issued instantly.
Most eSIMs install by scanning a QR code. Set it up over Wi-Fi before you travel. Airalo, Holafly and Nomad let you buy and manage plans in an app.
Some plans throttle after a daily cap. For example, Airalo's unlimited drops to 1Mbps after 3GB/day, and Sakura's au unlimited caps tethering. Check each provider's fair-use policy before you buy.
