2008 was the 400th anniversary of Takatora TODO's relocation from Imabari in Shikoku to Iga Ise, which is part of the capital's metropolitan area, and so a commemorative celebration of the 400-year anniversary of his entry into the capital area was held at Ueno-jo Castle, during which ancient documents written by Takatora were put on display.
なお、2008年は藤堂高虎が四国今治から伊賀伊勢に入府して400年になり、上野城では入府400年祭を開催し、高虎公直筆の古文書の展示を行っている。
