Hayashi Naotoshi served as a bushō from the Sengoku to early Edo periods. During the Edo period, he served as a retainer of the Fukuoka domain in Chikuzen Province. As a retainer of the Kuroda clan, he was included among a group of retainers called the Twenty-Four Elite of the Kuroda.
His former wife was the daughter of Kuroda Taketoshi and later wife the daughter of Nagami Sadachika (the uncle of Nagami Sadachika (written with a different character)).
In 1569, Naotoshi was born as the second son of Matsumoto Naomitsu in Karuizawa in the Saku District of Shinano Province. He was a retainer of the Takeda clan, but, after a defeat at the Battle of Nagashino, his family moved to Yamada in Ise Province. When traveling by a vessel owned by a merchant from Ise named Kadoya Shichirō-jirō, he came ashore in Himeji in Harima Province and then became a servant of Kuroda Yoshitaka. Later, upon orders of Yoshitaka, he received the surname of Hayashi Daigaku (a resident of Akashi in Harima) and adopted the name of Hayashi Tarōemon.
In the third month of 1584, he had his first experience in combat at the Battle of Kishiwada. In 1586, during an assault on Urutsu Castle, Naotoshi, along with Mori Tomonobu, served at the front of the attack. In 1588, he received a fief of 514 koku. During the Bunroku-Keichō Campaign, Naotoshi served as the head of an infantry battalion. In the second month of 1594, he became the only known individual in the midst of the conflict to kill a tiger with a spear. The tiger struggled against the spear, causing a bend in the neck of the spear. Kuroda Nagamasa recognized the achievement by naming the sword toratsuki, or Tiger Thrust. The sheath was made from impressive hawk feathers so adopted as an insignia of the Kuroda family. Naotoshi took a young girl who lost her parents and relatives in the war to Japan, named her Sato, and raised her as his daughter. Later, she entered the priesthood at the Kinryū Temple and adopted the name of Myōseini. Around this time, he engaged in the construction of Fushimi Castle in the environs of Kyōto.
In 1598, his fief was increased to 903 koku. In 1600, at the Battle of Kisogawa-Gōtogawa and the Battle of Sekigahara, Naotoshi served valorously under Kuroda Nagamasa. He served as a messenger for taking over Najima Castle in Chikuzen. Later, when the castle was abandoned, he received one of the gates from the castle which he reused for the gate to his residence. The Hayashi were the only family among members of the Kuroda clan permitted to have a two-story gate.
In 1601, Naotoshi was granted landholdings of 3,000 koku encompassing the village of Haji in the Kaho District of Chikuzen. In 1610, during the construction of Nagoya Castle, he was responsible for building the stone walls and eastern main gate in one of the sections assigned to the Fukuoka domain.
From around 1614, he called himself Kamon-no-suke.
On 11/30 of Kanei 6 (1629), Naotoshi died in his residence in Fukuoka. He was sixty-one years old.
For a long time, the toratsuki spear was missing, but an individual who returned to the city of Fukuoka (his hometown) from the United States possesses the spear. The long-blade spear was manufactured by the Nobukuni school of swordsmiths in Yamashiro Province during the Nanbokuchō period. The spear is known as a suyari featuring a somewhat shorter coulisse than a spear known as a nihongō manufactured in the latter part of the Muromachi period.
