Ryōgoku Kokugikan
Tochiazuma's "danpatsu-shiki", or official retirement ceremony, took place on 2 February 2008 at the Ryōgoku Kokugikan, with around 10,000 people in attendance. Coming from Tokyo, he naturally had a huge supporters network in the capital, and the event was a sell-out. He had lost a noticeable amount of weight since his retirement.
