If you're in need of some outdoor excitement, make a day trip to Mt Komaki. No easy stroll around the block, this hike is great for some mid-vacation exercise.
You'll find Mt Komaki in the farming city of Komaki. It's free to visit, so you can leave your credit card zipped up in your daypack. While you're in these parts, why not also visit some other worthwhile sights, such as Meiji Mura, Mozo Wonder City and Park Arena Komaki?
