period of remarkable commercial and cultural development that influenced modern Japan, alongside a series of major natural disasters.<\/p>\n<p>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.<br \/>\nHe was succeeded by Tokugawa Tsunayoshi, who later became famous for the Shorui Awaremi no Rei (Edicts on Compassion for Living Things).<br \/>\nThis 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.<\/p>\n<p>The Establishment of Mitsui Echigoya (1673): In 1673 (Enpo 1), Mitsui Takatoshi opened the Echigoya kimono shop in Nihonbashi Honcho, Edo.<br \/>\nThe business eventually developed into what is now the Mitsukoshi department store.<br \/>\nMitsui introduced an innovative retail system based on cash sales at fixed prices, eliminating the traditional practice of selling primarily on credit and negotiating prices.<br \/>\nThis revolutionary approach transformed commercial practices in Edo and contributed significantly to the development of Japanese retail trade.<\/p>\n<p>The Development of Wasan (Japanese Mathematics, 1674): In 1674 (Enpo 2), the mathematician Seki Takakazu published Hatsubi Sanpo, an important mathematical treatise.<br \/>\nHe developed original algebraic methods known as Tenzan-jutsu, which used a distinctive system of written mathematical notation.<br \/>\nHis achievements greatly advanced Japanese mathematics and established him as one of the most influential mathematicians of the Edo period.<\/p>\n<p>NBTHK
