Soemu Toyoda
After the Americans began attacking Japanese installations in the Bonin Islands on 10 October 1944, the aircraft of the Fourth Carrier Division were ordered to prepare for combat by the commander of the Combined Fleet, Admiral Soemu Toyoda. Two days later, the 634th Naval Air Group was reassigned to the Second Air Fleet and began flying to bases in southern Kyushu, among these were nine D4Ys and a dozen E16As assigned to "Ise" and "Hyūga". On 14 October they attacked the aircraft carriers of Task Force 38 near Formosa with little effect and heavy losses. The following day Nakase was promoted to rear admiral.
