Lantravel

I'm an engineer, and I started Lantravel after seeing how often a single network failure turns a Japan trip into a scramble: a missed train, a map that won't load, a translation app spinning when you actually need it.

Most Japan eSIMs sell you one network. Every Lantravel order includes two native Japanese carrier eSIMs: KDDI as the main line, plus a SoftBank backup. If the first one fails, you switch on your phone — no support ticket, no waiting on customer service.

We're not the cheapest, and that's intentional. The price is higher because both cards are included. If you care more about a stable connection than finding the lowest fare, this is who it's for.
