SECTION II -- OVERVIEW
Born in 1546 in Harima Province, Kuroda Yoshitaka — almost universally called by his court name Kanbei — became one of the three or four sharpest strategic minds of the Sengoku.He met Hideyoshi during the Chūgoku campaigns and immediately attached himself, planning the brilliant water siege of Takamatsu Castle in 1582 that pinned the Mōri at the moment of Honnō-ji.
It was Kanbei who, on hearing the news of Nobunaga's death, told Hideyoshi 'this is your great chance' — a remark that, decades later, Hideyoshi would joke had been the day he learned to fear his own retainer.After unifying Kyūshū for the Toyotomi he was reduced to the modest 120,000 koku Nakatsu domain, well below his merit, because Hideyoshi could not bear having him close to the capital.
He became a Christian (baptismal name Simeon Josui) before the Bateren Edict, and at Sekigahara — though formally aligned with the West — covertly built his own army on Kyūshū with the apparent intention of seizing the island for himself if both sides exhausted each other in Mino.

“Strategy is choosing what not to do.”
SECTION V -- FIELD NOTES
[A]The Letter at Honnō-ji
When the courier reached Bitchū with news that Nobunaga was dead, Hideyoshi wept — and Kanbei, the only one in the tent who saw clearly, leaned in and said: 'Your moment has come.' Hideyoshi later told this story to others as a joke, but added that he never let Kanbei near the capital again.
SECTION VI -- LEGACY & IMPACT
Kanbei is the patron saint of Japanese strategists. Hagakure singles him out as the supreme example of what a samurai brain could accomplish, and modern Japanese business writing routinely cites him in the same breath as Miyamoto Musashi. His son Nagamasa founded the Fukuoka domain, the Kuroda 520,000 koku that lasted to the Meiji Restoration.
