Mitsui Hachirōemon (三井 八郎右衛門) is the inherited name given to the first son born to the head family (総領家, Sōryō-ke), or the leading branch of the extended Mitsui family. It was Mitsui Takatoshi (三井高利) who started the naming ritual that a male heir would be called Hachirōemon when they decide the next leader of family business that Mitsui was known for. For those sons of Takatoshi, each bloodline had a nickname: the first son Takahira held the Kita branch, the second son Takatomi the Isarago branch (伊皿子家), and the third son Takaharu the Shimmachi branch (新町家).

When the first son of Kita branch be too young to inherit the position from his father, one of his uncles or male cousins would be selected to fill in for a limited period of time, but they did not count him as a Hachirōemon. The extended family decided to expel Takayoshi (高美) who had consumed family fortune by indulging in antiquity as hobby, thus Takayoshi's younger brother Takahisa was acted as Hachirōemon until Takakiyo, his nephew, was old enough.

Mitsui Takahira (三井 高平, 24 May 1653 – 17 January 1738) was the first of the Mitsui head family, or the Kita branch.^[1] As the eldest son of Mitsui Takatoshi and the original Kita branch, Takahira's younger brothers and their family would support Kita branch by having their sons adopted to. Mitsui family business was sustained as cousins and uncles worked as an interim head of the company, and both Takakata and Takahisa were not called Mitsui Hachirōemon.

Mitsui Takatomi (三井 高富, 1654 – 12 June 1709), the second son of Takatoshi, was the second head of the Mitsui family. His descendants headed the Isarago branch.

Mitsui Takafusa (三井 高房, 16 April 1684 – 7 November 1748) was the third head of the Mitsui family. He was the son of Takahira.

Mitsui Takakata (三井 高方) was the son of Takaharu, the third son of Takatoshi and the first head of the Shinmachi branch. Although not counted as such, when Takafusa retired as the third head in 1734, his successor Takayoshi was still young, so Takakata acted as Hachirōemon.

Mitsui Takayoshi (三井 高美, 1715 – 1782) was the fourth head of the Mitsui family. His childhood name was Manzō (万蔵). In 1733, he was appointed Kan'emon (勘右衛門), and inherited the Kita branch while his father's Takafusa became a Buddhist monk the following year. Renamed himself Shinpachi (新八) in 1736, succeeded into the Kyoto money order business under the title of Saburōsuke (三郎助) in 1738, and in 1741, following the death of his uncle Takakata, Takayoshi succeeded as Hachirōemon. However, as Takayoshi incurred a large amount of debt from Ōmotokata (大元方) by spending too much on personal art collection as well as making huge donations to Saikyō-ji [jp] Temple, his title of Hachirōemon was passed to Takafusa in 1747 through the intentions of his younger brother Takahisa, who was the head of the Shinmachi representing the interest of the extended Mitsuis at the time. In 1750, Takayoshi handed over the Kita branch to his second son Takakiyo, but the squandering was not settled, so in August 1756, Mitsuis negotiated with Takayoshi and made an agreement that they paid him 1200 kan retirement pension, and Takayoshi agreed to withdraw from Mitui's financial business. Nonetheless, however, it was discovered that Takayoshi secretly borrowed money from Ōmotokata, and in the same year on 13 November, his successor, Takakiyo (then Shinpachi), decided to disown him officially: an application form was filed to the city financial officials on the 27th of the same month, in which Takakiyo signed the consent of 87 businessmen and employees that his uncle Takahisa would act as Hachirōemon.

Mitsui Takahisa (三井 高弥), the son of Takafusa, succeeded as the third head of the Shinmachi branch as the adopted son of Takakata. Although not counted as such, when his older brother, the fourth head, had his title as Hachirōemon revoked in 1747, Takahisa acted as Hachirōemon.^[2]
