The International Dateline is truly a fascinating thing. It’s like a magic wand of time that can both give and take, depending which way you head. Each time my family and I fly back to the Midwest, the space time continuum is seemingly suspended. Leave Tokyo at 4:00 pm, touch down in the Midwest at 2:00 pm, and then reach our final destination by 5:00 pm of the same day. Over 15 hours of travel that appears to have been compressed within the span of one single hour. I still can’t wrap my head around it at times.
This dateline has a way of slightly altering our perspective of historical events. Most Americans are familiar with the following quote from President Franklin Delano Roosevelt: “December 7th, a date that will live in infamy.” The date to which he refers is the day on which the Combined Fleet of the Japanese Imperial Navy under the command of Admiral Isoroku Yamamato attacked the elements of the US Pacific fleet at Pearl Harbor. However, this is the narrative from the American side of the International Dateline. The December 24th edition of Shashin Shuhou (Photographic Weekly), a morale boosting propaganda magazine published in Japan from the 1938 until mid-1945, carried the following headline for its graphic two-page artist’s depiction of the attack: “Shattering the dawn: Attack on Pearl Harbor, December 8th”. The Japanese government christened the 8th day of each month as Taisho Hotaibi (literally means “Day to Reverently Accept the Imperial Edict”) to commemorate the great victory over the United States at Pearl Harbor and the Imperial declaration of war on the US and its allies (the day also served to regularly renew nation’s fervor and commitment to the war effort). Was Pearl Harbor a great victory for the Japanese? The answer to this question depends on the context in which the attack is viewed. From a purely military engagement view, it is safe to say that it was a resounding success, but did this single engagement succeed in shaping the course of the upcoming conflict? This is the question that the Mainichi Shinbun explored in the third installment of its series “Numbers tell a tale—Looking at the Pacific War through data” (the original, in Japanese, is here). True to the narrative on this side of the Pacific, this article was released on December 8th last year. Just as with the other installments in the series, it presents a slew of data that helps to put historical events into context. (more…)
