Perfect hiking companion app
It pulls together bear sighting reports from all over Japan into a single map, which is huge because otherwise you'd be trying to piece together scattered local news articles in Japanese. Being able to see recent activity near wherever I was staying gave me way more confidence planning day hikes and trail runs.
A couple of times it actually made me rethink a route, which I'm glad about in hindsight. Even if you're not a hardcore outdoors person, if your trip takes you anywhere rural — onsens in the mountains, temple walks, cycling routes, it's worth having on your phone just for the peace of mind. Nothing else like it that I could find.
