No it isn't. The Nodachi appears to be clamped fully when assembled. However, the support does not extend through the majority of the base plate so the vast majority of the blade does not have the support that the sides do. See the red circle in the first pic below.
Compare that to the Era in the following two pics. In the first, you can see that the top cap and base plate touch at the leading edge across the entire span of the blade.
In the second, you can see how the blade support does not change across the full width, while the Nodachi does.
Btw, this isn't a hit against Tatara. They make amazing stuff and I'm a big fan. I just want to correct this one post.
