The Imperial Palace Inui street is open to public twice a year, cherry blossoms season and autumn leaves season for 9 days each. The number of participants is about 400,000 in spring and 200,000 in autumn. Inui street (The picture is the entrance, Sakashita gate) is generally restricted only to royal family members and Imperial household agency officials, so many people from all over Japan, and recently more and more foreign visitors, rush to take this opportunity to enter the restricted zone to see. This event is yearly conducted but everyone feels it is special this year. That is because the Imperial throne is scheduled to be succeeded to by the crown prince at the end of this month, then it was announced that the name of Japanese calendar is changed from Heisei to Reiwa.
