Another Staff Headquarters

When some of the Combined Fleet staff (specifically Admiral Ugaki) balk at the idea of sending badly needed destroyers to escort the Mirai, Lt. Commander Taki proposes that a new submarine, the I-21, be sent instead, with himself on board to observe. Yamamoto reminds Taki that he is essentially protecting Japan's future — and without Japan, there is no navy. However, Taki retorts — silently — that without the navy, there can be no Japan. In Japan, Kusaka and General Ishiwara develop a plan to create Kusaka’s vision of Zipang, an undefeated Japan, with its economic heartland in Japanese-dominated Manchuria. Specifically, Kusaka reveals the 1959 oil strike at Daqing, Heilongjiang Province, in Manchuria, which could supply many times Japan's needs for decades.
