I am neither engineer nor architect, which is probably why the dearth of lateral bracing in the roof scares me. In a country where the primary stress is gravity working upon arches, where the load is composed almost entirely of the arches themselves, fine. However, in the Tokyo Metropolitan District, the stress comes from side-to-side motion of varying intensity and wavelength, several times a year. The immense window spaces in between the structural elements, with only a few gargantuan linkages, look like invitations to disharmonic disaster.
