The Ronin were detained, and treated with courtesy and respect, due to their Samurai status. The Tokugawa Shogun and his entourage were profoundly impressed by the Samurai Spirit demonstrated by the 47 Ronin.
The shogunate was troubled, deliberating for almost 2 months. By killing Kira and avenging the death of Asano, the Ronin followed the Way of Bushido, but they also acted against the authority and laws of the Shogun himself, who prohibited personal vendetta.
On February 4, 1703, the 47 Ronin were divided into four groups and handed over to four different daimyo, who were ordered to supervise and witness their deaths.
As they were expecting it, the 47 Ronin were sentenced to die honorably by committing seppuku, and not as vulgar criminals.
Oishi Kuranosuke and the valiant 47 Ronin bravely committed seppuku as they were commanded by the Shogun. They were buried side by side next to their master, Lord Asano Naganori at Sengaku-ji Temple in Edo.
Today in Sengaku-ji Temple, you can still see well preserved kimonos, arms, armors and drums that were used by the 47 Ronin during the attack against Kira's mansion. You can also see their gravestones and the famous Kubi-Arai well (head washing well) they used to clean up Kira's head on the night of the attack.
For the Japanese people, the tombs of the 47 Ronin became a place of great veneration and prayer, and have been visited by hundreds of thousands of admirers that come to burn incense at their tomb, venerating them as symbols of loyalty and true Samurai Spirit.
