I'm planning on traveling to Japan for 3 weeks at the end of April, specifically April 21 - May 10. I know that during this period will be the abdication of the throne by the current emperor. Since the emperor doesn't change very often in Japan (last one was when I was 1 year old XD), I wanted to experience as much of the culture surrounding the abdication as possible. I was wondering: Are there any events happening in Tokyo surrounding the abdication of the emperor during this time period? A cursory Google search I tried turned up nothing, but I'd be very disappointed if I didn't try every avenue available to me and ended up missing something important.
(Secondary question, while I'm on the topic: The new emperor is scheduled to be enthroned on October 22, if memory serves. I'm thinking of going back to Japan around then if there are going to be events to experience at that time)
Thanks!
