Ueno Park is vast. In addition to the zoo and art museums, there are many historic temples, and even a full day isn't enough to see everything. Once, while walking through the park, I unexpectedly came across Kaneiji Temple. It sparked my curiosity and made me want to learn about the historical background of its construction. Kaneiji Temple was founded in 1625 by High Priest Tenkai, a close confidant of Tokugawa Ieyasu. It was built to pray for the stability of the shogunate and peace throughout the land, and it was also an important temple for the Tokugawa shogun family. The temple grounds were once enormous, covering the entire area that is now Ueno Park. Most of its buildings were destroyed by fire during the Battle of Ueno at the end of the shogunate, but you can still feel the solemnity and historical depth of this ancient temple today. Walking through the grounds, the atmosphere forms a striking contrast with the lively park, naturally making you slow down and take in the traces of the Edo period left behind by time.
