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, Osaka Castle, with surrounding point of interests to start your trip off with a bang.
For day 2, we recommend exploring the center side of town.
For day 3, we bundled attractions like ABENO HARUKAS and Abeno Harukas 300 - Observation deck and other places within a close range, so that the time it takes to travel between all of them is less than one hour.
Turn this guide into a shared trip: add flights, accommodation, transport notes, and reservations so your whole group can edit one timeline.
