Zenjubo Sugitani/Origin

Origin
Sugitani Zenjubō was pushied with one of the most brutal decapittaions, as he had attempted to assassinate Oda Nobunaga, a prominent daimyo in 1570. After being caught, Zenjubō was buried alive in the ground with only his head out, and the head was slowly sawn off with a bamboo saw by passers-by for several days. These unusual punishments were abolished in the early Meiji era.
