Stories of the Japanese 00708 [Late Kamakura Period] The 92nd Emperor Fushimi (Jimyoin-to Lineage)

In the 10th year of Koan (1287), there was a major development in the conflict within the Imperial Court between the Jimyoin-to lineage (Retired Emperor Go-Fukakusa) and the Daikakuji-to lineage (Retired Emperor Kameyama).
The court noble Saionji Sanekane had long been at odds with Retired Emperor Kameyama and had been leaning exclusively toward Retired Emperor Go-Fukakusa. However, it was an era dominated by the Daikakuji-to, and Retired Emperor Kameyama was in control of the cloistered government. In the first year of Kenji (1275), Prince Hirohito, the son of Retired Emperor Go-Fukakusa, was named Crown Prince, signaling that the throne would eventually return to the Jimyoin-to lineage, but twelve years had passed without any sign of an abdication.
Sanekane thought that by winning the Shogunate over to his side, he could somehow restore the Jimyoin-to's influence, so he pleaded with Taira no Yoritsuna. Since Yoritsuna also had the intention of avoiding Retired Emperor Kameyama, who was on friendly terms with Adachi Yasumori, their interests aligned.
On October 12, Taira no Yoritsuna's son, Munetsuna, went to the capital and visited the Saionji residence,
to convey the Shogunate's intention that "the Crown Prince must ascend to the throne, and Retired Emperor Go-Fukakusa must hold the cloistered government."
Upon hearing this, Retired Emperor Kameyama hurriedly sent envoys to Kamakura to negotiate, but the Shogunate had no intention of responding. With no other choice, on October 21, Emperor Go-Uda abdicated in favor of Prince Hirohito. This marked the birth of Emperor Fushimi. Furthermore, with the accession of Emperor Fushimi, the cloistered government of his father, Retired Emperor Go-Fukakusa, began.
In contrast to the Daikakuji-to, which had maintained friendly relations with the Adachi clan, the Jimyoin-to, having formed an alliance with Taira no Yoritsuna, began to act as they pleased by borrowing the authority of the Shogunate.
In February of the following year, Koan 11 (1288), Emperor Fushimi's son, Prince Tanehito (the future Emperor Go-Fushimi, 1288–1336), was born, and on April 25 of the second year of Shoo (1289), he was named Crown Prince. This was a clear indication of the intent to have the Jimyoin-to produce emperors for two consecutive generations. At the time, there were voices of despair among the Daikakuji-to, fearing they might never be able to produce an emperor again.
The Jimyoin-to also consolidated positions within the Imperial Court with their own faction. On July 11 of the first year of Shoo (1288), Emperor Fushimi appointed Kyogoku Tamekane (1254–1332) as Kurodo no To (Head Chamberlain). The Kurodo no To served a role similar to that of a secretary to the Emperor.
Kyogoku Tamekane was a renowned poet who established a major poetic school known as the "Kyogoku School." The Kyogoku School advocated for the free use of language, rejecting traditional waka conventions, and became highly influential, centered around the Jimyoin-to. Furthermore, Emperor Fushimi had received waka instruction from Kyogoku Tamekane since his time as Crown Prince and is known as one of the most distinguished poets among the successive emperors.
Thus began the era of the Jimyoin-to, allied with Taira no Yoritsuna.
