When I went, I believe the special exhibition price was separate. I remember skipping the exhibition because we really wanted to see the garden the exhibition at the time we were not interested in. I’m pretty sure but. This is several months ago. Make sure to walk around the area afterwards some nice shops even if it’s just window shopping.

I think Nezu museum is closed between the seasonal exhibitions. Next exhibition will start from April 15th, 2018. You can check the schedule on the museum's web site.

Depends on how interested you are in old Chinese artifacts and how much you are interested in gardens. Two very different things. When I was there (mid-September 2017) there was so many Chinese artifacts that I felt like I'd seen enough for a lifetime. I spent about two hours in the museum and two hours in the garden. If I went back, I'd take a good camera and spend 1 hour in the museum and 3 in the garden. Others will have different views.

Yes the admission is $7 to $10 i believe!

It is in the central Tokyo.

The Nezu Musuem will open again on Tuesday 13 April with a new exhibition. It is always closed on Monday but open from Tuesday to Sunday every week except when they are installing a new exhibition. There is a good website in English. Be sure to tour the garden and have tea at the teahouse. We lived across the street for several years in the 1970s but the museum has been rebuilt and expanded since those days.
