Nobushige's brother Takeda Shingen 15211573 also made alike observations: "One who was born in the house of a warrior, despite of his rank or class, 1st acquaints himself with a man of military feats and accomplishments in loyalty... Everyone knows that if a man does not hold filial piety toward his own parents he could also neglect his duties toward his lord. Such a neglect means a disloyalty toward humanity. so such a man does not deserve to be called 'samurai'."
The feudal lord Asakura Yoshikage 14281481 wrote: "In the fief of the Asakura, one shouldn't find out inherited chief retainers. A man should be assigned as indicated by his capability and loyalty." Asakura also observed that the successes of his father were acquired by the kind treatment of the warriors and common people living in domain. By his civility, "all were wanting to sacrifice their lives for him and become his allies."
Kato, Kiyomasa was one of the most powerful and well known lords of the Sengoku Era. He commanded most of Japan's big clans throughout the invasion of Korea 15921598 , and in a handbook he addressed to "all samurai, despite of rank" he told his followers that a warrior's only responsibility in life was to "grasp the long and the short swords and to die". He also ordered his followers to put forth great effort in studying the military classics, particularly those related to loyalty and filial piety. he's best recognized for his quote: "If a man doesn't investigate into the matter of Bushido daily, it'll be hard for him to die a courageous and manly death. it's essential to engrave this business of the warrior into one's mind well."
Nabeshima Naoshige 15381618 AD was another Sengoku daimyo, who fought alongside Kato Kiyomasa in Korea. He stated that it was shameful for any man to haven't risked his life at least once in the line of responsibility, despite of his rank. Nabeshima's sayings could be passed down to his son and grandson and could become the base for Tsunetomo Yamamoto's Hagakure. he's best recognized for his saying "The way of the Samurai is in desperateness. Ten men or more can not kill such a man."

Torii Mototada 15391600 was a feudal lord in the service of Tokugawa Ieyasu. On the eve of the fight of Sekigahara, he volunteered to remain behind in the doomed Fushimi Castle while his lord advanced to the east. Torii and Tokugawa both agreed that the castle was indefensible. In an act of loyalty to his lord, Torii chose to remain behind, pledging that he and his men could fight to the finish. As was custom, Torii vowed that he could not be taken alive. In a dramatic last stand, the garrison of 2,000 men held out against overwhelming odds for ten days against the big army of Ishida Mitsunari's 40,000 warriors. In a moving last declaration to his son Tadamasa, he wrote:
"It isn't the Way of the Warrior to be shamed and avoid death under situation that aren't especially important. It goes without saying that to sacrifice one's life for the sake of his master is an unchanging principle. That I can go ahead of the other warriors of this country and lay down my life for the sake of my master's benevolence is an honor to my family and was my most fervent want for many years."
it's said that both men cried when they parted ways, because they knew they could never see each other again. Torii's father and grandfather had served the Tokugawa before him and his own brother had been killed in fight. Torii's actions changed the course of Japanese history. Ieyasu Tokugawa could effectively increase an army and win at Sekigahara.
The translator of Hagakure, William Scott Wilson observed examples of warrior stress on death in clans other than Yamamoto's: "he Takeda Shingen was a rigorous disciplinarian as a warrior, and there's an exemplary story in the Hagakure relating his execution of two brawlers, not because they had fought, but because they hadn't fought to the death".
