Upbringing:

Regardless of the truth about Musashi's ancestry, when Musashi was seven years old, the boy was raised by his uncle, Dorinbo (or Dorin), in Shoreian temple, three kilometers (~1.8 mi.) from Hirafuku. Both Dorin and Musashi's uncle by marriage, Tasumi, educated him in Buddhism and basic skills such as writing and reading. This education is possibly the basis for Yoshikawa Eiji's fictional education of Musashi by the historical Zen monk Takuan. He was apparently trained by Munisai in the sword, and in the family art of thejutte. This training did not last for a very long time, as in 1589, Munisai was ordered by Shinmen Sokan to kill Munisai's student, Honiden Gekinosuke. The Honiden family was displeased, and so Munisai was forced to move four kilometers (~2.5 mi.) away to the village of Kawakami.

In 1592, Munisai died, although Tokitsu believes that the person who died at this time was really Hirata Takehito.

Musashi contracted eczema in his infancy, and this adversely affected his appearance. Another story claims that he never took a bath because he did not want to be surprised unarmed. While the former claim may or may not have some basis in reality, the latter seems improbable. An unwashed member of the warrior caste would not have been received as a guest by such houses as Honda, Ogasawara, and Hosokawa. These and many other details are likely embellishments that were added to his legend, or misinterpretations of literature describing him.

His father's fate is uncertain, but it is thought that he died at the hands of one of Musashi's later adversaries, who was punished or even killed for treating Musashi's father badly. However, there are no exact details of Musashi's life, since Musashi's only writings are those related to strategy and technique.

 

Training in swordsmanship:

The name "Musashi" was thought to be taken from the name of a warrior monk named Musashibō Benkei who served under Minamoto no Yoshitsune, but this is unconfirmed.

It is said that he may have studied at the Yoshioka-ryū dojo (school), which was also said to be the school Musashi defeated single-handedly during his later years, although this is very uncertain. He did have formal training either by his father until he was 7 years old or from his uncle beginning at the age of 7. Ultimately the name was taken from his own original kanji, 武蔵, which can be read as Takezō or as Musashi, as stated in Eiji Yoshikawa's book Musashi.

 

First duel:

I have trained in the way of strategy since my youth, and at the age of thirteen I fought a duel for the first time. My opponent was called Arima Kihei, a sword adept of the Shinto ryū, and I defeated him. At the age of sixteen I defeated a powerful adept by the name of Akiyama, who came from Tajima Province. At the age of twenty-one I went up to Kyōtō and fought duels with several adepts of the sword from famous schools, but I never lost.

—Miyamoto Musashi, Go Rin No Sho

 

According to the introduction of The Book of Five Rings, Musashi states that his first successful duel was at the age of thirteen, against a samurai named Arima Kihei who fought using the Kashima Shintō-ryū style, founded byTsukahara Bokuden (b. 1489, d. 1571). The main source of the duel is the Hyoho senshi denki ("Anecdotes about the Deceased Master"). Summarized, its account goes as follows:

In 1596, Musashi was 13, and Arima Kihei, who was traveling to hone his art, posted a public challenge in Hirafuku-mura. Musashi wrote his name on the challenge. A messenger came to Dorin's temple, where Musashi was staying, to inform Musashi that his duel had been accepted by Kihei. Dorin, Musashi's uncle, was shocked by this, and tried to beg off the duel in Musashi's name, based on his nephew's age. Kihei was adamant that the only way his honor could be cleared was if Musashi apologized to him when the duel was scheduled. So when the time set for the duel arrived, Dorin began apologizing for Musashi, who merely charged at Kihei with a six-foot quarterstaff, shouting a challenge to Kihei. Kihei attacked with a wakizashi, but Musashi threw Kihei on the floor, and while Kihei tried to get up, Musashi struck Arima between the eyes and then beat him to death. Arima was said to have been arrogant, overly eager to battle, and not a terribly talented swordsman.

—William Scott Wilson, The Lone Samurai

 

Travels and duels:

 

In 1599, three years later, Musashi left his village, apparently at the age of 15 (according to the Tosakushi, "The Registry of the Sakushu Region", although the Tanji Hokin Hikki says he was 16 years old in 1599, which agrees time-wise with the age reported in Musashi's first duel). His family possessions such as furniture, weapons, genealogy, and other records were left with his sister and her husband, Hirao Yoemon.

He spent his time traveling and engaging in duels, such as with an adept called Akiyama from the Tajima Province.

In 1600, a war began between the Toyotomi and Tokugawa clans. Musashi apparently fought on the side of the Toyotomi's "Army of the West", as the Shinmen clan (to whom his family owed allegiance) had allied with them. Specifically, he participated in the attempt to take Fushimi castle by assault in July 1600, in the defense of the besieged Gifu Castle in August of the same year, and finally in the Battle of Sekigahara. Some doubt has been cast on this final battle, as the Hyoho senshi denki has Musashi saying he is "no lord's vassal" and refusing to fight with his father (in Lord Ukita's battalion) in the battle. Omitting the Battle of Sekigahara from the list of Musashi's battles would seem to contradict the Go Rin No Sho's statement that Musashi fought in six battles, however. Regardless, as the Toyotomi side lost, it has been suggested that Musashi fled as well and spent some time training on Mount Hiko.

 

 Ichijoji Sagarimatsu, location of the battle between Musashi and the Yoshioka school

After the battle, Musashi disappears from the records for a while. The next mention of him has him arriving in Kyoto at the age of 20 (or 21), where he began a series of duels against the Yoshioka School. Musashi's father, Munisai, also fought against a master of the Yoshioka school and won 2 out of 3 bouts in front of the shogun at the time, Ashikaga Yoshiaki who granted him the title of "Unrivaled Under Heaven". The Yoshioka School (descended from either the Tenshin Shōden Katori Shintō-ryū or the Kyo-hachi-ryū) was the foremost of the eight major schools of martial arts in Kyoto, the "Kyo-ryū" / "Schools of Kyoto". Legend has it that these eight schools were founded by eight monks taught by a legendary martial artist resident on the sacred Mount Kurama. At some point, the Yoshioka family also began to make a name for itself not merely in the art of the sword but also in the textile business and for a dye unique to them. They gave up teaching swordsmanship in 1614 when they fought in the Army of the West against Tokugawa Ieyasu in the Battle of Osaka, which they lost. But in 1604, when Musashi began duelling them, they were still preeminent. There are various accounts of the duels — the Yoshioka family documents claim that there was only one, against Yoshioka Kenpō, which Musashi won.

Musashi challenged Yoshioka Seijūrō, master of the Yoshioka School, to a duel. Seijūrō accepted, and they agreed to a duel outside Rendaiji in Rakuhoku, in the northern part of Kyoto on 8 March 1604. Musashi arrived late, greatly irritating Seijūrō. They faced off, and Musashi struck a single blow, per their agreement. This blow struck Seijūrō on the left shoulder, knocking him out, and crippling his left arm. He apparently passed on the headship of the school to his equally accomplished brother, Yoshioka Denshichirō, who promptly challenged Musashi for revenge. The duel took place in Kyoto outside a temple, Sanjūsangen-dō. Denshichirō wielded a staff reinforced with steel rings (or possibly with a ball-and-chain attached), while Musashi arrived late a second time. Musashi disarmed Denshichirō and defeated him. This second victory outraged the Yoshioka family, whose head was now the 12-year old Yoshioka Matashichiro. They assembled a force of archers, musketeers and swordsmen, and challenged Musashi to a duel outside Kyoto, near Ichijō-ji Temple. Musashi broke his previous habit of arriving late, and came to the temple hours early. Hidden, Musashi assaulted the force, killing Matashichiro, and escaping while being attacked by dozens of his victim's supporters. To escape and fight off his opponents he was forced to draw his second sword and defend himself with a sword in each hand. This was the beginning of his niten'ichi sword style. With the death of Matashichiro, this branch of the Yoshioka School was destroyed.

After Musashi left Kyoto, some sources recount that he travelled to Hōzōin in Nara, to duel with and learn from the monks there, widely known as experts with lance weapons. There he settled down at Enkoji Temple in Banshū, where he taught the head monk's (one Tada Hanzaburo's) brother. Hanzaburo's grandson would found the Ensu-ryū based on the Enmei-ryū teachings and iaijutsu.

From 1605 to 1612, he travelled extensively all over Japan in musha shugyō, a warrior pilgrimage during which he honed his skills with duels. He was said to have used bokken or bokuto in actual duels. Most of the engagements from these times did not try to take the opponent's life unless both agreed, but in most duels, it is known that Musashi did not care which weapon his foe used — such was his mastery.

A document dated 5 September 1607, purporting to be a transmission by Miyamoto Munisai of his teachings, suggests Munisai lived at least to this date. In this year, Musashi departed Nara for Edo, during which he fought (and killed) a kusarigama practitioner named Shishido Baiken. In Edo, Musashi defeated Musō Gonnosuke, who would found an influential staff-wielding school known as Shintō Musō-ryū. Records of this first duel can be found in both the Shinto Muso-ryu tradition and the Hyōhō Niten Ichi-ryū (Miyamoto Musashi's school). The Shinto Muso Ryu tradition states that, after being defeated by Musashi, Muso Gonnosuke beat Musashi in a rematch. There are no current reliable sources outside the Shinto Muso Ryu tradition to confirm that this second duel took place.

Musashi is said to have fought over 60 duels and was never defeated, although this is a conservative estimate, most likely not accounting for deaths by his hand in major battles. In 1611, Musashi began practicing zazen at the Myōshin-ji temple, where he metNagaoka Sado, vassal to Hosokawa Tadaoki; Tadaoki was a powerful lord who had received the Kumamoto Domain in west-central Kyūshū after the Battle of Sekigahara. Munisai had moved to northern Kyūshū and became Tadaoki's teacher, leading to the possibility that Munisai introduced the two. Nagaoka proposed a duel with a certain adept named Sasaki Kojirō. Tokitsu believes that the duel was politically motivated, a matter of consolidating Tadaoki's control over his fief.

 

Duel with Sasaki Kojirō:

On April 13, 1612, Musashi (about age 30) fought his duel with Sasaki Kojirō, who was known as "The Demon of the Western Provinces" and who wielded a nodachi. Musashi came late and unkempt to the appointed place — the island of Funajima, in the Kanmon Straits separating Honshū and Kyūshū. The duel was short. Musashi killed his opponent with a bokken that legend says he had carved from an oar used on the boat that carried him to the island. Musashi's late arrival is controversial. Sasaki's outraged supporters thought it was dishonorable and disrespectful, while Musashi's supporters thought it was a fair way to unnerve his opponent. Another theory is that Musashi timed the hour of his arrival to match the turning of the tide. The tide carried him to the island. After his victory, Musashi immediately jumped back in his boat and his flight from Sasaki's vengeful allies was helped by the turning of the tide. Another theory states he waited for the sun to get in the right position. After he dodged a blow, Sasaki was blinded by the sun.

Musashi briefly established a fencing school that same year.

 

Later life and death:

 

Six years later, in 1633, Musashi began staying with Hosokawa Tadatoshi, daimyo of Kumamoto Castle, who had moved to the Kumamoto fief and Kokura, to train and paint. Ironically, it was at this time that the Hosokawa lords were also the patrons of Musashi's chief rival, Sasaki Kojirō.[clarification needed] While there he engaged in very few duels; one would occur in 1634 at the arrangement of Lord Ogasawara, in which Musashi defeated a lance specialist by the name of Takada Matabei. Musashi would officially become the retainer of the Hosokowa lords of Kumamoto in 1640. The Niten Ki records "[he] received from Lord Tadatoshi: 17 retainers, a stipend of 300koku, the rank of ōkumigashira 大組頭, and Chiba Castle in Kumamoto as his residence."

In the second month of 1641, Musashi wrote a work called the Hyoho Sanju Go ("Thirty-five Instructions on Strategy") for Hosokawa Tadatoshi; this work overlapped and formed the basis for the later Go Rin No Sho. This was the year that his third son, Hirao Yoemon, became Master of Arms for the Owari fief. In 1642, Musashi suffered attacks of neuralgia, foreshadowing his future ill-health. In 1643 he retired to a cave named Reigandō as a hermit to write The Book of Five Rings. He finished it in the second month of 1645. On the twelfth of the fifth month, sensing his impending death, Musashi bequeathed his worldly possessions, after giving his manuscript copy of theGo Rin No Sho to the younger brother of Terao Magonojo, his closest disciple. He died in Reigandō cave around June 13, 1645 (Shōhō 3, 30th day of the 4th month). The Hyoho senshi denki described his passing:

At the moment of his death, he had himself raised up. He had his belt tightened and his wakizashi put in it. He seated himself with one knee vertically raised, holding the sword with his left hand and a cane in his right hand. He died in this posture, at the age of sixty-two. The principal vassals of Lord Hosokawa and the other officers gathered, and they painstakingly carried out the ceremony. Then they set up a tomb on Mount Iwato on the order of the lord.

Musashi died of what is believed to be thoracic cancer,[citation needed] and was not killed in combat. He died peacefully after finishing the Dokkōdō ("The Way of Walking Alone", or "The Way of Self-Reliance"), 21 precepts on self-discipline to guide future generations.

His body was interred in armor within the village of Yuge, near the main road near Mount Iwato, facing the direction the Hosokawas would travel to Edo; his hair was buried on Mount Iwato itself. (NB - Mount Iwato is part of the Mount Kinpo range in Kumamoto and actually where Musashi wrote the Book of Five Rings in the Reigando cave. His grave is not there, but about 45 minutes away, to the east and on the other side of Kumamoto, in the Musashizuka area). Some of his remains were given to Mimasaka so that he could be buried (in part) with his parents. The Mimasaka graves are located in the precincts of Musashi Shrine.

Nine years later, a major source about his life — a monument with a funereal eulogy to Musashi — was erected in Kokura by Miyamoto Iori; this monument was called the Kokura hibun. An account of Musashi's life, the Niten-ki二天記, was published in Kumamoto in 1776, by Toyota Kagehide, based on the recollections of his grandfather Toyota Masataka, who was a second generation pupil of Musashi.
