Ikoma clan

During the Heian period, descendants of Fujiwara no Fusasaki moved to Ikoma District (生駒郡), Yamato Province (now part of Heguri District (平群郡), Nara Prefecture) from which the clan took its name.

The founder of the clan, Ikoma Iehiro (生駒家広), who lived during the Muromachi period moved to Niwa District (丹羽郡), Owari Province to escape the Ōnin War. He was a samurai merchant who lived at Ko-ori Castle (小折城) and accumulated wealth by storing ashes and oils for dyes and used bashaku to transport his goods.

The Ikoma clan genealogy records Ikoma Iehiro as a descendant of Fujiwara no Tameyoshi (藤原為義) but the names of the generations in between are missing. Fujiwara no Tameyoshi was a great-grandson of Fujiwara no Tokihira and a ninth generation descendant of Fujiwara no Fusasaki who founded the "Northern House" of the Fujiwara clan (Fujiwara Hokke, 藤原北家).

Another theory is that the brother of Tameyoshi, Fujiwara no Nobuyoshi (藤原信義), became Ikoma Shōji (生駒庄司) and began using the name Ikoma. In any case, the ancestors are the same.

Ikoma Chikamasa (1526–1603).

During the time of Ikoma Iemune (生駒家宗), the third head of the clan, Inuyama Castle (犬山城) in Owari Province belonged in to Oda Nobuyasu (織田信康). Nobuyasu's nephew Oda Nobunaga (織田信長) began visiting the Ikoma family mansion and approached them for their financial strength and knowledge of the surrounding area. Due to the Battle of Okehazama in 1560 the Ikoma had a brief respite from Nobunaga and were able to conduct business freely in the territory.[2]

The clan became relatives of Oda Nobunaga when Ikoma Iemune's daughter, Ikoma Kitsuno (生駒吉乃) became a concubine of Nobunaga. She had previously been married to Yaheji Dota who died in the Battle of Akechi. After the loss of her husband, Kitsuno returned to her family's home, Ikoma mansion and it was there that she met Nobunaga. It was believed that Oda Nobunaga was charmed by Kitsuno's beauty at first sight, and immediately took her as his concubine. Nobunaga was officially married to Lady Nō, the daughter of Saitō Dōsan, but it was believed that theirs was not a happy marriage, especially since Nōhime could not conceive. It is often thought that Kitsuno was Nobunaga's most beloved concubine and that she probably had a higher position than Nōhime. In 1557 Kitsuno gave birth to Nobutada and later Nobukatsu and Tokuhime (Lady Toku). In 1564, Kitsuno moved to Kori Castle (in present-day Kōnan, Aichi). She suffered due to the difficulty of her childbirths, and in 1566 she died at the age of 29. Even though Nobunaga is often regarded as a callous and bellicose figure, it is said that Nobunaga mourned her throughout the night and had her buried within view of his castle. Her body was cremated and buried in the cemetery at Kyusho temple (the Ikoma family temple), in Tashiro town. Nobunaga gave his son Nobukatsu the area in which Kyusho temple lies in order to protect it and Kitsuno's tomb, out of respect for his treasured concubine. Her brother, Ikoma Ienaga became Nobunaga's stable master (umamawari, 馬廻).[3]

At Ikoma mansion (Ko-ori Castle, 小折城) there was a well known episode when Nobunaga's sandle-bearer, Kinoshita Tōkichirō (木下 藤吉郎), who was later known as Toyotomi Hideyoshi asked Kitsuno to mediate to help him become an officer. He also heated up straw sandles on his bossom and gave them to Nobunaga. There was a strong geographical and blood relation with the Hachisuka clan (蜂須賀氏) of Kawanami-shū (川並衆).[4]

Both Ikoma Ienaga, the fourth clan head and his son Ikoma Toshitoyo, the fifth clan head, served Oda Nobunaga with 1900 koku annual stipend. After the Honnō-ji incident when Nobunaga was assassinated, they served his second son Oda Nobukatsu (織田信雄). After Nobukatsu was forced to become a monk the Ikoma clan became rōnin and so became retainers of Toyotomi Hideyoshi.

At the Battle of Sekigahara they joined the forces of Fukushima Masanori. Ikoma Chikamasa was part of Ishida Mitsunari's force while his son, Ikoma Kazumasa was part of Tokugawa Ieyasu's force. Chikamasa remained at Sanuki and sent his retainers in his stead to attack Tanabe castle in Tango Province. He chose this strategy to preserve the Ikoma clan regardless of which side prevailed. Because Kazumasa fought in Ieyasu's force, Ieyasu allowed Chikamasa to rule his existing domain after the battle, but Chikamasa took responsibility for fighting on the losing side by transferring the headship of the family to Kazumasa. He became a priest and withdrew to Mount Kōya. He was soon permitted to return to Sanuki Province. In 1603, he died in Takamatsu castle.[5]

Ikoma Kazumasa (1555–1610).

After the war the main line of the Ikoma clan were asked by Tokugawa Ieyasu to be the bannermen for Matsudaira Tadayoshi when he entered Owari Province but after the death of Tadayoshi they became retainers of Tokugawa Yoshinao as samurai of the Owari Domain.

The fifth clan head was Ikoma Toshitoyo (生駒利豊). His older brother, Ikoma Yoshinaga (生駒善長), created a new branch of the family known as the Awa-Ikoma family (阿波生駒家). His sister Jikouin (慈光院) became wife of the lords of the Tokushima Domain (徳島藩)

After the sixth clan head, Ikoma Toshikatsu (生駒利勝), the clan received an annual stipend of 4,000 koku in the Owari Domain and in the aftermath of the Meiji Restoration they became consultants for the Owari-Tokugawa family.
