Geology
The seamount is very close to the "V"-shaped bend in the Hawaiian-Emperor seamount chain, and thus would be useful in understanding the exact age of the bend. Although few dredge samples are available, they have all been reliably dated at 47 million years (Sharp and Clague, Science, 313, 1281–84, 2006), during the Eocene epoch of the Paleogene period. During the cruise SO112 of the ''R/V SONNE'', high resolution bathymetric mapping was conducted, showing that Daikakuji is nearly in diameter and nearly in height, with a summit lying underwater. Because of its flat capped top, Daikakuji is considered a guyot. A smaller, younger, secondary guyot just east of the main mass overlaps its slope. The western site suffered a large collapse sometime in its history, evident by a large slump, that likely carried away a significant part of the volcano's caldera. Daikakuji Seamount has some well developed rift zones oriented towards the Emperor portion of the chain, whereas the younger, secondary cone has rift flanks in the direction of the Hawaiian ridge.See also
