Battleship Mutsu Memorial Museum
Mutsu's battle history isn't as storied as some of the older Japanese battleships. The Kongo-class in particular were upgraded to keep up with fleet carriers, and literally left slower ships like Mutsu behind in their wake.

Book Review: Five eyewitness accounts from the Pacific War
What follows here is less a book review than an annotated bibliography; in my studies of the Imperial Japanese Navy I found that there are hundreds of secondary sources (many of them excellent), but the primary source data, particularly in English, can be harder to find. At the same time, Western sources can lose sight of the primary subject matter and cloud the historiography with implicit (and sometimes explicit) bias.

Kanrin Maru Memorial - San Francisco
San Francisco's Lincoln Park, situated on the northwest of the peninsula, is home to several memorials and monuments. Among these are military fortifications, a Holocaust Memorial, and a marker for the end of the Lincoln Highway. Situated among these landmarks, not far fron a statue of El Cid, is the Kanrin Maru Memorial. This place marks a seminal event in pacific history; the first time a Japanese ship made landfall in the United States, in 1860.

Traces of the Second World War in and around Iwakuni 岩国
MCAS Iwakuni is situated on an island formed by the divergence of the Nishiki River into the Monzen and Imazu Rivers, emptying into Hiroshima Bay just south of Miyajima. Much of the area was purchased by the Imperial Japanese Army in 1938; the following year saw the establishment of the Iwakuni Naval Air Group 岩國海軍航空隊, a flight training command working in tandem with the Imperial Japanese Navy academy at Etajima.

The end of the Second World War
The effect of the atomic bombs, the collapse of Manchuria, and the general devastation on the Japanese mainland from constant Allied air raids all informed the decision to end the war. The following day, 10 August, the Konoe government informed the Allies that it would accept the terms of the Potsdam Declaration.

Atomic Bombing of Nagasaki
A B-29 named 'Bockscar' took off from Tinian in the Marianas, and finding the primary target of Kokura obscured by cloud cover and smoke, dropped its bomb on the secondary target, Nagasaki City. The bomb missed its target by approximately 3 km, exploding halfway between the naval arsenal and the Mitsubishi armament works.

Miyako-Jima, Okinawa, Japan
When reading about this monument, and the story behind it, I can't help but think of the gesture of friendship, and how things would change between the two countries. In 1876, the Japanese were rapidly modernizing, rapidly industrializing and working harder than anybody to gain a seat at the international table; Imperial Germany was the inspiration behind many of these reforms.

Early submarines of the Imperial Japanese Navy - Kure, Hiroshima, Japan
Ready for combat by 1905 but too late to take part in the conflict with Russia, the ships were used as training vessels, and were later joined by no. 6 and 7, as Kawasaki Shipyard in Kobe bought plans directly from Holland and built them under the supervision of two of his assistants.

OTD: Birth of Yamamoto Isoroku
Perhaps best known for his 'sleeping giant' comment issued immediately following the attack on Pearl Harbor, he has been somewhat sanitized in recent scholarship as an anti-war figure (he was not). Yamamoto was fated to preside over a series of quick victories in the early days of the Pacific War, only to be caught up in his own complicated plans at Midway.

On this day: Tohoku Earthquake and Tsunami - March 11, 2011
The earthquake, the strongest in recorded Japanese history, set off a series of tsunamis that killed 18,000 throughout the northeast coast of the country. Iwate, Miyagi, and Fukushima prefectures had all but a hundred or so of the casualties. The tsunami that struck Fukushima knocked the power out in the Dai-ichi nuclear plant, which led to a partial meltdown.

On this day: Attack on Pearl Harbor - December 7, 1941
Tropes and banners and slogans aside: could we do it again? Do we have the infrastructure, the know-how, frankly, the patriotism to rebuild a shattered fleet and take it to the enemy? Could we bring a broken DDG or LCS up from the mud and have it fighting in six months?

Momotaro, the Peach Boy of Japan
Whether or not Momotaro was born from a peach, or from a woman who ate the peach, is one area of disagreement. His age is another; some sources have him at 30 years old at the time of his expedition to defeat the oni; others have him at 15.

The Five Routes of Edo Period Japan
Hello PHG fans, we're back today with another Japan post. I recently watched a YouTube video from the fantastic NaruMasa Travel youtube channel . One of the many reasons I watch their travel videos (aside from the beautfiul photography) is that they typically look for historic sites that are easily accessible but not necessarily well-known. In a recent video , they explore Tsumago-Juko, the 42nd of 69 stops on the Nakasendo Road. This town, and neighboring Magome-Juko, have b

Aichi Prefecture and Tokugawa Ieyasu
Aichi Prefecture 愛知県 in the Chubu Region of Japan is home to a wide variety of things to see and do. From iconic Mt. Fuji to snowy Nagano and the rice fields of Niigata, there's incredible food, outdoor activities, and charming villages to see and visit. The cornerstone of this prefecture is Nagoya, the fourth-largest city in Japan by population and one of the more diverse of Japan's many urban sprawls.
