How detailed is the daily itinerary on a guided tour?

First time booking a guided tour (Japan, 12 days) and I’m the kind of person who plans every hour of a trip. The tour page just has a general outline like “Day 3: Kyoto temples and gardens” which is… vague.

Do you eventually get a more detailed day by day schedule with actual times? Like “8am breakfast, 9am bus to Kinkaku-ji, 11am free time” etc? Or is it really just “you’ll find out when you get there”? I need to mentally prepare for either approach lol. Also, how much free time is typical per day? I want to make sure I can explore on my own sometimes.
