The Downfall of Two Brothers

I’ve talked about the first shogun of Japan’s new Kamakura government, Minamoto no Yoritomo and his betrayal of his vassals here and here, but I also alluded to his execution of his younger half-brother, Minamoto no Yoshitsune. Yoshitsune’s downfall is indeed a sad tale. But as we’ll see, Yoritomo’s own downfall, while slower, wasn’t much better.

Minamoto no Yoshitsune was a military genius and the youngest of nine sons of Minamoto no Yoshitomo (Yoritomo was the oldest). When Yoshitomo was executed by his rival, Taira no Kiyomori, the half brothers were all scattered in exile, but gradually reunited under Yoritomo. Out of these brothers, Yoshitsune was the most talented in warfare. Yoshitsune led the led against the Heike clan and eventually destroyed it in the battle of Dan-no-ura.

Yoshitsune has been celebrated throughout Japanese history as the ultimate warrior, who along with his companion Benkei, went on many adventures and fought many battles. Yoshitsune’s bravery and unconventional strategies, coupled with Benkei’s stalwart strength and loyalty have been the subject of many Noh and Kabuki plays, as well as many works of art.

But one thing Yoshitsune was not good at was politics. Once the Heike were destroyed, tensions rose between the new military commander (shogun 将軍), namely his older half-brother Yoritomo, and the conniving emperor Go-Shirakawa. The Imperial family had lost power due to the Heike clan, and were eager to get it back. The Genji clan defeated the Heike and weren’t keen to hand over their hard-fought power.

Yoshitsune was caught between these two men, and used as a proxy for their struggle for power. The Emperor, grateful for Yoshitsune’s efforts appointed him Kebiishi (検非違使): the Sheriff of Kyoto the capitol. Accepting this position, however, meant that Yoshitune was now working under the Emperor, not his half-brother the Shogun, and Yoritomo was evidentially furious by this. From here on out, he began to suspect his baby brother of plotting to overthrow him. The historical drama, Thirteen Lords of the Shogun, implies that certain retainers, perhaps jealous of Yoshitsune, may have been whispering in Yoritomo’s ear, fanning his paranoia further. When Yoshitsune tried to return to Kamakura to talk to his brother directly, he was refused entry and had to idle in the nearby town of Koshigoé.

While staying at Koshigoe, Yoshitsune wrote the following letter to his older brother:

So here I remain, vainly shedding crimson tears….I have not been permitted to refute the accusations of my slanderers or [even] to set foot in Kamakura, but have been obliged to languish idly these many days with no possibility of declaring the sincerity of my intentions. It is now so long since I have set eyes on His Lordship’s compassionate countenance that the bond of our blood brotherhood seems to have vanished.

Yoshitsune was unable to ease his older brother’s concerns, nor did he want to be under control of the Emperor either, so he bowed out, and retreated to the province of Ōshū way up north, where he had previously been exiled. It was familiar land, and the ruler of Oshu promised to watch Yoshitsune on behalf of Yoritomo, while also protecting him from Yoritomo. With his mistress, Shizuka,² they moved there and things were quiet for a time.

However, Yoritomo wasn’t satisfied. When Yoshitsune’s keeper passed away, the keeper’s son hatched a plan with Yoritomo to allow Yoritomo’s troops to attack his Yoshitsune’s house.

Legends hype up this last stand by Yoshitsune (with Benkei defending), but in any case, Yoshitsune the famed military commander was killed by his own half-brother, and his head was preserved in a box with sake. Yoshitsune was later enshrined as a kami at Shirahata Shrine in Fujisawa.³

Yoshitsune died in 1189, and by 1192 Yoritomo was in full control of Japan since the Emperor had died as well. As the shogun, the supreme commander of military forces, no one could oppose Yoritomo any longer, the country had been pacified at last, and he had avenged his father for his wrongful death.

……..but, this came at a steep, steep price. Yoritomo had to dodge other assassination attempts, and spent the remaining years of his life constantly watching his back. He had paid for his power in blood and betrayal, and even after taking tonsure as a Buddhist monk,⁴ he never really found any peace. When he died at age 51, more than a few probably sighed in relief. Yoritomo was powerful, and crafty, but he was brutal and paranoid, and everyone around him spent their lives in constant fear. One can not help but see the similarities to certain dictators today.

P.S. if you go to Tsurugaoka Hachimangu shrine in Kamakura, Japan, you can see a tiny museum, just to the left of the inner sanctum, which has relics from Yoritomo’s life. It’s easy to miss, but tickets are cheap, and it’s amazing to see. We saw it in December 2022, just after watching the historical drama, and it was pretty amazing. The new, larger museum near the front entrance is also great. A visitor can easily spend half a day at Tsurugaoka Hachimangu, especially if you are a history nerd.

P.P.S. Official website for Shirahata Shrine in Fujisawa. No English, sorry, but it’s close to Fujisawa station if you’re in the neighborhood.

¹ I couldn’t find a good translation of Kebiishi in English, but based on the duties, and based on varied definitions of “Sheriff” in English-speaking countries, this seemed the closest equivalent. Needless to say, being the sheriff of the capital city was a prestigious honor, but also comes with plenty of political strings attached.

² Another revered character in the plays and art about Yoshitsune. Yoshitsune had married another one for political reasons, and Shizuka was technically his concubine, but they seemed to have genuinely loved one another and so she alone stayed with Yoshitsune at Oshu. She is often revered for her sincere, loving devotion, and for their doomed fate.

³ When we visit family friends in Japan, we often go to Fujisawa. It’s a nice seaside town, but I never knew that Yoshitsune was enshrined here. I might try to stop by one of these days and get a stamp for my book.

⁴ A Buddhist monk, as in an bhikkhu or renunciant. More on the terminology here. The practice of retiring to the monastic life was a common practice among the nobility in pre-modern Japan. His wife, Hojo no Masako, not only retired to the monastic life, but still took the reins of power after Yoritomo’s death becoming the famous “warlord nun“. Go-Shirakawa, the scheming emperor, had technically retired to the monastic life as well, but only as a means of dodging certain constraints on his power by the Fujiwara clan. Politics were…. complicated in those days, and few who retired truly let go of power, despite the Buddhist prohibition for Buddhist monks to be involved in politics. Then again, even now some monks fail to heed this prohibition either. Once again, politics and religion should not mix.

Also, at the risk of being sanctimonious, I wonder if Yoritomo’s Buddhist devotion did him much good in the afterlife, given how many people he had murdered. This is not unlike the ancient king in India, Ajatashatru, who while devoted to the historical Buddha Shakyamuni, had also murdered his way to the top. Because of the weight of his crimes, Ajatashatru’s devotion and progress on the Buddhist path was greatly hindered for many lifetimes to come according to Shakyamuni. I can’t help but think Yoritomo suffered the same fate. In other words, we all pay our debts some time.
