Tama Aqueduct Saigoku 33 Kannon Pilgrimage

The Tamagawa Aqueduct was constructed by the Tokugawa Shogunate to supply drinking and fire-fighting water from the Tama River to Edo in 1653.  More than half a century later, the Tama Aqueduct Kannon Pilgrimages were organized at the same time.  Their organizers must have been very systematic as they organized 100 temples at a time.  However, the pilgrimages didn't become popular and little is known of their history.  As far as I have virtually visited the Tama Aqueduct Saigoku 33 Kannon Pilgrimage, I haven’t found any super-popular temple, while most other organizers of such pilgrimages in Edo tried to include such a super-famous temple as Senso-ji Temple.
