Kumamoto Castle, how long for visiting?

I know the answer to my question depends on the people, but generally how long a person should take to visit the castle?

Even fast-paced travelers who do not want to see all should allocate at least 45 minutes. But if you want to see everything, incl. Hosokawa Villa, you can spend half a day.

For the average visitor I recommend 90-120 minutes.

Thank you very much for the informations, Uji! I hope I can visit the Suienji too the same day. Unfortunately, maybe I will not have enough time to visit the Hosokawa Villa...

Uji's estimates sound just about right.

I was there back in 2013. Seeing everything at the castle will probably take hours, but the people in charge seem to have thought of that in advance and planned a couple of suggested routes for visitors, each emphasising a certain aspect of the castle architecture. I believe there may also have been a third option. I expect the pamphlet you'll get at the ticket booth will have the routes plotted out along with the expected time required for each.
