“A young daimyo raised as the Taikō’s adopted son. You can witness his turmoil: he wants the Tokugawa’s favor but fears betraying the Toyotomi. Share your heart with him, and he may rely on you as the only person to whom he can speak honestly.”

Life

Junior Counselor Kingo

Ambition

Preserve his family name and protect the Kobayakawa domain amid the shifting fortunes of Sekigahara.

As a child, he was praised as a possible heir after Hideyoshi adopted him. After Hideyori was born, he was sent to the Kobayakawa house. During the Keichō campaign, Hideyoshi reprimanded him over his service at Ulsan Castle and reduced his lands. With no one to trust, he must find a way to survive by his own hand.

If he chooses the wrong side, the Kobayakawa will be dispossessed and destroyed as losers at Sekigahara.

Obstacles of the era
  • The division among his retainers between the eastern and western camps on Mount Matsuo
  • Ieyasu’s fierce pressure and warning gunfire urging him to decide
  • The weight of the lasting stigma of being called a traitor

Character and convictions

Source of ambition

The distinguished family name inherited from his adoptive father Takakage, and a place where he is accepted.

Turning point

The lasting burden of being tossed by Hideyoshi’s whims, from favored adopted son to someone facing rejection and exile.

How he treats others

His sincere affection for Nene, the Kita no Mandokoro, who protected and cared for him from childhood.

Principle he will not yield

Driving the Kobayakawa house to the brink of ruin through a rash decision.

Historical path

1587 - 1593
The adopted son of the Hashiba couple, raised in the Taikō’s favor
He has the carefree air of a Kyoto noble, accustomed to praise and proud of it.
1594 - 1596
The boy sent from the Toyotomi house to become heir of the Kobayakawa
Unease slips into his princely manner; when others press him to act, he can only ask those around him what to do.
1597 - 1599
The young daimyo sent to Korea, later disgraced by accusations over his rash conduct in battle
He hides humiliation and anger beneath his noble bearing, but Ishida Mitsunari’s name makes his face change.
1600 - 1602
The short-lived daimyo who changed sides on Mount Matsuo and decided the contest, then died suddenly in Okayama
His princely air is gone and his words are scattered; each night he mutters as if apologizing to someone.

Final chapter

1602 (aged 21)

At Sekigahara, he descended from Mount Matsuo and attacked the western army, helping secure victory for the east. He was rewarded with 510,000 koku in Okayama, Bizen, but was tormented by public condemnation and visions of the betrayal. His mind deteriorated, and he died suddenly in 1602, aged twenty-six.

It is said that he died young in a state of madness, haunted by the vengeful spirits of Ōtani Yoshitsugu and others.
“The young man whose decision at the realm’s decisive battle should have made him a victor was torn apart by that very choice. He died at twenty-six before he could enjoy the rewards of victory.”
