An ok museum.
Was cheap to get into but is quite small.
The Buddha exhibition hall was most interesting, a lot of good stuff in there.
The other part of the museum not no good - mainly scrolls and paintings.
Also each temple has it’s own museum (usually about 500yen to enter each one) which have the artefacts specific to that temple. These museums are much better than the Nara National one, my suggestion is skip the National museum and use you money (and time) to enter several of the temple museums instead. The Kofuku-Ji museum and Todaiji museums were both great.
