Yoriichi Tsugikuni was one of the most powerful and legendary Demon Slayer during the Sengoku Era in ancient Japan. As the inventor of Breath of the Sun, the first and most powerful Breath Style, Yoriichi played a pivotal role in the battle against demons. Though his exact lifespan is unknown, historians estimate that Yoriichi lived approximately 500 years ago during the 1500s. This means around 5 centuries have passed since the legendary swordsman met his end.
When Did Yoriichi Live?
Though the exact dates of Yoriichi’s birth and death are unclear, most records indicate he was active as a Demon Slayer during the mid to late Sengoku Period in 16th century Japan. This was a tumultuous time of social upheaval and near constant military conflict between warring states.
During this era, demons also proliferated across the land, preying on humans and wreaking havoc. Yoriichi dedicated his life to slaying these demons and protecting the innocent. Based on the technology, events, and figures that are referenced in relation to Yoriichi, historians place him specifically in the mid 1500s.
Key Evidence
Several key facts point to Yoriichi having lived during the mid 1500s:
- He used swords and tools consistent with that time period in Japan.
- The political figures referenced were active in the mid 16th century.
- His brother Michikatsu Tsugikuni founded the Tsugikuni style during this era.
- The demons he fought correlate with known activity and figures from folklore during the 1500s.
By cross referencing the people, events, and technology detailed in Yoriichi’s legend, a clear picture emerges placing him in the mid to late 1500s.
When Did Yoriichi Die?
Though the precise year is unknown, most evidence suggests Yoriichi likely died sometime around 1570-1580, meaning approximately 440-450 years have passed since his death. Some key indications include:
Age at Death
By all accounts, Yoriichi lived to an extraordinarily old age, even by modern standards. Various sources estimate he was over 100 years old when he died. Given his birth around the 1510s and the common lifespans of the era, this points to him passing in the 1570s or 1580s.
Length of Career
Based on the scope of battles and events referenced in Yoriichi’s legend, historians estimate his career battling demons spanned 70-80 years. If he began in his 20s during the 1530s, this again aligns with him meeting his end between 1570-1580.
References to Successors
The immediate successors and disciples of Yoriichi’s Breath Style seem to have flourished in the late 1500s into early 1600s, indicating Yoriichi passed his torch sometime in the preceding decades.
