Opened in 1853 while the shogun still reigned, this small and rather corny amusement park is Japan's oldest. It offers a small roller coaster, a kiddie Ferris wheel, a carousel, a haunted house, a 3-D theater, samurai and ninja shows, and other diversions that appeal to younger children. Note, however, that after paying admission, you must still buy tickets for each ride; tickets are ¥100 each, and most rides require three to four tickets.
