Zipang - Season 1 Episode 9 Deadline

Tsuda reveals that, in addition to the crew of the tanker, he has put together a sizable task force at Singapore around the cruiser Kashii for dealing with the mystery ship that he has been ordered to investigate, should it become necessary. However, Kusaka and Kadomatsu convince Tsuda that force will not work and ensure that the Mirai is fueled and provisioned accordingly. Tsuda has an opportunity to tour the Mirai but has difficulty coping with knowledge of the future. Kusaka tells Tsuda that the future is not fixed as recorded in Mirai's history, since its very presence is actively forcing changes, and that their job is to ensure that these lead to a "better" future for Japan. Specifically, he informs Tsuda that he intends to convince Captain Umezu and Admiral Yamamoto to change the outcome of the Battle of Guadalcanal. Captain Umezu accepts Kusaka's suggestion, though with much difficulty, and calls for a meeting of the senior officers to plan their moves.
