Opened in 1853 while the shogun still reigned, this small and rather corny amusement park is Japan’s oldest. It has a small rollercoaster, a kiddie Ferris wheel, a carousel, a haunted house, a 3-D theater, and other diversions appealing to younger children. New is the Telepathy Walker, a headset device that lets you “see” how Hanayashiki has changed over the years. Note, however, that after paying admission, you must still buy tickets for each ride (except for the Telepathy Walker, which is free but available only to people 12 and older). Tickets are ¥100 each, and most rides require two to four tickets.
