August 22, 2026
Reflecting on today's history, we explore the proclamation of Tokugawa Iemitsu as Shogun, the full opening of the Iwaki Line of Japan Railway, and the twenty-four solar term 'Shosho'.

1623 — Proclamation of Tokugawa Iemitsu as Shogun On August 23, 1623, Tokugawa Iemitsu was formally announced as the Shogun of the Edo Shogunate. This event marked the foundation for the stable rule of the shogunate and played a significant role in the cultural and political landscape of the Edo period. Understanding this era is essential for comprehending Japanese culture.

1898 — Complete Opening of the Iwaki Line In 1898, the Iwaki Line (now JR Joban Line) section from Tabata to Iwanuma was fully opened, becoming an important railway connecting Tokyo with northern areas. Today, the Joban Line remains a vital route for commuting and travel, offering useful information for foreign tourists planning day trips from Tokyo.

Shosho — A Day Signifying the End of Heat Shosho is one of the twenty-four solar terms indicating the gradual end of summer heat and the approach of autumn. While some regions might still experience lingering heat, it is a good time to appreciate the end of summer. Foreign residents in Japan can enjoy observing the changing seasons of nature during this period.
