Launch your City Tour this morning with an orientation drive that will take you past the National Diet (Japanese Parliament) and Tokyo Tower, once the tallest building in Tokyo. Stop at the Imperial Palace Plaza, from where you can view the two bridges that form the entrance to the inner grounds of the Imperial Palace, the primary residence of the Emperor of Japan. Continue to Tokyo's Gateway to the North, the Ueno district, and visit Ameyoko Street Market, once a black market selling American goods after World War II. Watch how this thriving hub is frequented by locals seeking the best bargains, then visit the Sensō-ji Buddhist temple in Asakusa, which has been rebuilt countless times since it was founded in 628, making it Tokyo's oldest temple site. Pass through the vermilion-lacquered Kaminarimon Gate and stroll down Nakamise shopping street soaking up the shitamachi (downtown Tokyo) atmosphere. Next, make a stop in Ginza and enjoy some free time for shopping. The rest of the afternoon is at leisure.
