You may have heard that Meshtastic is "free and open source." But what does that actually mean? And why should you care?

The short answer is yes. You can use Meshtastic legally in Japan, as long as your device has Giteki certification.

Taking Meshtastic devices into the field for the first time? Run through this checklist before you go.

Imagine your team is spread across a mountain. No mobile signal. You need to know where everyone is and whether they are okay. How do you stay in touch?

Welcome to Karida. We are glad you are here.

We started this company because we care about rural Japan. Small towns, mountain villages, farming communities. These places face real challenges every day. Communities are getting smaller and older. Budgets are tight, and there are fewer people to do the work. At the same time, the need for safety, coordination, and local resilience keeps growing.
