30 days · 20GB · $22.89, or 10GB for $14.55 in lighter months
Used it all? It slows to 384 kbps instead of billing you
Kyoto today, Fukuoka on Thursday: one setup, no re-install
Staying longer than a month? That's what the form is for.
知恵
Cafes are fine for email, not for calls. Coworking day passes run $10-20 in every big city.
Fukuoka and Osaka beat Tokyo on rent; the shinkansen makes weekends anywhere.
The 90-day tourist stamp allows no Japanese employment. Remote work for a foreign employer is common practice; check your own situation.
Golden Week and Obon book out months ahead; plan city-hops around them.

Not at purchase. Each plan says at checkout whether its days begin when you install it or when it first connects in Japan.
About two minutes. We email a QR code; scan it before you fly and forget about it.
One-for-one replacement, and any unused plan is refunded.
It depends on the plan, and checkout shows it before you pay. Hotspot uses the same data.
