Kōrakuen & Akihabara Tokyo

This swathe of central Tokyo runs alongside the Soto-bōri, the former outer moat of Edo Castle, and the Kanda-gawa. From west to east there's the old geisha district of Kagurazaka and the hallowed grounds of controversial shrine Yasukuni-jinja. In Kōrakuen the dazzling traditional garden Koishikawa Kōrakuen is a highlight, as is watching a baseball game at neighboring Tokyo Dome. Further east, browse the bookshops of Jimbōchō, the traditional restaurants of Kanda, and the electronic, pop-culture and contemporary-craft emporiums of Akihabara.
