One of the many sites used by the Tokugawa Shogunate in the Edo period to execute criminals, Christians and conspirators – it is believed around 10,000 people were killed here. Methods included burning, boiling, crucifixion and some were hung upside down to drown as the tides rose – so basically, pretty gruesome. If that’s your idea of sightseeing though – this is a great spot! There is a memorial and remnants including a well, a burning post and a stone base for erecting the crucifixion pillars. You can also see the bridge of tears – where families and loved ones would say goodbye to the condemned.
