No, didn't get out to the studios, but we did see some Godzilla sights:
Toho's Nichigeki Theater (now in the glass Yurakucho Mullion)
Wako Dept Store
National Diet Building
Kachidoki Bridge
Yurakucho Mullion
Fuji TV
And from my favorite movie, the Tokyo Big Sight
Tokyo Metropolitan Govt Tower
Uh-oh
Godzilla didn't visit here, but it's still an important kaiju landmark
(That wasn't Tokyo Tower toppled in Gojira'54. The tower was built in 1958)
