Get 15% off your first eSIM
No coupon-site scavenger hunt, no expired codes copied from forum threads — WELCOME is our own welcome code, published here at the source. Enter it on your first order, here on the site or in the Japan eSIM app, and land in Tokyo with your plan already discounted.
WELCOME 
How to redeem it
-
Open the plan list right here in the browser — nothing to download first — before the airport rush.
-
Pick the Japan data plan that matches your trip, whether it's a long weekend in Tokyo or a month from Hokkaido to Okinawa.
-
Type WELCOME in the promo code field at checkout and pay the discounted price. Your eSIM is ready before you take off.
The honest fine print: WELCOME works on your first order, here on the site or in the app, and takes a flat 15% off at checkout. And the code has no expiry date, so there is no countdown to race.
