1. The Hexagram Barrier Mystery Protecting Sendai
Indispensable to understanding Sendai Toshogu is the legend of the “hexagram” (rokubosei) that encircles the Sendai castle town.
It is said that Date Masamune, the founder of the domain, arranged key jinja in a specific pattern to create a massive spiritual barrier (kekkai) to protect Sendai from disasters. Sendai Toshogu is situated at the “northeast” (kimon, or ‘demon’s gate’) point of this hexagram. By enshrining Ieyasu, a symbol of the Edo shogunate, the Date clan is believed to have sought the strongest protective power.
When the vertices of this hexagram are connected, a precise geometric shape emerges. Even today, occult enthusiasts whisper that “Date Masamune’s urban planning might have been a magical array.”
2. The 100,000 Ryo Debt and a Hidden Story of “Loyalty”
Why did the Date clan construct such a magnificent Toshogu? The truth reveals a poignant drama of “repaying a debt of gratitude.”
During the era of Date Tadamune, the second lord, the Sendai domain suffered great fires and floods, pushing its finances to the brink of collapse. At that critical time, the domain averted disaster by borrowing a colossal sum of 100,000 ryo (worth hundreds of billions of yen today) interest-free from the shogunate.
To repay this immense debt of gratitude and to demonstrate the Date clan’s “unwavering loyalty to the shogunate,” Tadamune dedicated the domain’s full resources to building this Toshogu. This grand undertaking, spanning five years and involving over 800,000 laborers, was truly a project born of the Date clan’s pride.
3. The Ishi Torii That Traveled 700km Across the Sea
The imposing “ishi torii” (stone gate) standing at the entrance to the approach path is not made from stone quarried in Miyagi Prefecture.
It is made from granite specifically transported by sea from Inujima, Bizen Province (present-day Okayama Prefecture), the hometown of Furihime, Tadamune’s principal wife and a granddaughter of Ieyasu. Transporting such massive stone materials from the Seto Inland Sea all the way to Tohoku was an incredibly difficult feat at the time. This torii, symbolizing the deep ties between the Tokugawa and Date clans, still exudes dignity as the oldest stone torii in the prefecture.
4. “Messengers of Peace” Hidden in the Zuishinmon Gate
Take a close look at the hengaku (framed plaque) displayed on the Zuishinmon (gate with guardian figures), which is a National Important Cultural Property. There is a legend that the form of a “water bird” is subtly hidden within the characters spelling “Toshogu.”
Water birds are considered creatures that favor peace, and it is said that this inclusion expresses a wish for an end to an era of conflict and for long-lasting peace. When you visit, be sure to look closely and try to find it.
5. Pilgrimage Spot Information: Anime ‘Wake Up, Girls!’
Sendai Toshogu is also known as a pilgrimage site for the idol anime “Wake Up, Girls!”, which is set in Sendai.
In the series, characters are depicted visiting the jinja for Hatsumode (New Year’s shrine visit) and even training within the shrine precincts. The long stone staircase and the Zuishinmon, in particular, are highly accurately reproduced. Even today, it remains a popular spot visited by many fans, known as “WUGNERs” (fans of the work).
