Use this route structure as a starting point, then adapt stops and timing with your group in Journii.
For day 1, we strategically grouped the most popular attraction, Koboyama Park, with surrounding point of interests to start your trip off with a bang.
For day 2, we bundled attractions like Ōne Park and Mount Kōbō and other places within a close range, so that the time it takes to travel between all of them is less than one hour.
For day 3, these 4 places should be enough to fill your day with something exciting to do in Hadano.
Turn this guide into a shared trip: add flights, accommodation, transport notes, and reservations so your whole group can edit one timeline.
