Historical Background: The Enpo era (1673–1681) of the Edo period was a time of significant political transition, marked by a change in shogunal leadership.
It was also a period of remarkable commercial and cultural development that influenced modern Japan, alongside a series of major natural disasters.

The Death of the 4th Shogun, Tokugawa Ietsuna, and the Accession of the 5th Shogun, Tokugawa Tsunayoshi (1680): In 1680 (Enpo 8), Tokugawa Ietsuna, the 4th Tokugawa shogun, passed away.
He was succeeded by Tokugawa Tsunayoshi, who later became famous for the Shorui Awaremi no Rei (Edicts on Compassion for Living Things).
This period marked an increasingly significant transition from budan seiji (military-oriented government) toward bunji seiji (civil government), which placed greater emphasis on scholarship, Confucian principles, and proper etiquette.

The Establishment of Mitsui Echigoya (1673): In 1673 (Enpo 1), Mitsui Takatoshi opened the Echigoya kimono shop in Nihonbashi Honcho, Edo.
The business eventually developed into what is now the Mitsukoshi department store.
Mitsui introduced an innovative retail system based on cash sales at fixed prices, eliminating the traditional practice of selling primarily on credit and negotiating prices.
This revolutionary approach transformed commercial practices in Edo and contributed significantly to the development of Japanese retail trade.

The Development of Wasan (Japanese Mathematics, 1674): In 1674 (Enpo 2), the mathematician Seki Takakazu published Hatsubi Sanpo, an important mathematical treatise.
He developed original algebraic methods known as Tenzan-jutsu, which used a distinctive system of written mathematical notation.
His achievements greatly advanced Japanese mathematics and established him as one of the most influential mathematicians of the Edo period.
