In the closing days of World War II, a few days after the atomic bombings of Hiroshima and Nagasaki had completely eviscerated any faint hopes that Japan could win or even continue the war, the Japanese cabinet met to discuss and vote on the surrender of Japan and acceptance of the conditions set out in the Potsdam Conference. The vote was a tie, and nobody knew what to do or what was next.

Finally, Emperor Hirohito took decisive action, telling the cabinet members that the war had been lost and Japan would agree to the surrender terms. The fighting would end.

However, not everyone agree. In fact, some high-ranking military leaders decided to try to overthrow Hirohito and his planned surrender, continuing the war until every single Japanese was dead, if necessary. That was the only "honorable" possibility. Known historically as the Kyujo Incident, Japan's Longest Day is about this incident.

The day in question was August 14-15, 1945. Hirohito's recorded announcement of surrender was to be played on the 15th. On the night of the 14th Major Kenji Hatanaka and his men spent several hours searching for Hirohito's recording, a recording which was to be played for the nation at noon the next day. Unable to find the recording, the men occupied the NHK Building in an attempt to prevent the broadcast. Hatanaka had support from some factions of the military, but not quite enough to complete his coup. He abandoned the idea, went outside and killed himself.
It is important to know that while the general story is fairly well documented, parts of this graphic novel are speculation. The author opines that Hirohito had been blackmailed from the start to not oppose the war, even though he was generally against it. Potential historical reasons are given.

Two movies have been made about the Kyujo story: The 1967 film entitled, "Japan's Longest Day" and the 2015 film entitled, "The Emperor in August." Both movies are done in Japanese.

The overly picky could point out a few minor annoyances with the manga. First, there are half a dozen or so typos. Secondly, and perhaps it is a necessity and not an annoyance, is that the reader is swamped with many names and titles to keep straight.

One interesting touch is that the manga opens backwards from Western tomes, meaning the spine is on the right, not the left; so, the manga opens like old-style Japanese books did. This add to the authentic Japanese feeling of the manga, which was originally published in Japanese.

Japan's Longest Day is a gripping look at the anatomy of political decision-making under extreme duress. It shows that wars' conclusions can be as perilous and uncertain as wars' geneses. History buffs will be intrigued.
