Admission fee of Hanayashiki Amusement Park = 1000 yen ($9.71 € 7.09)

Until April 7th, my son is taking his spring break. He and my wife went to Hanayashiki Amusement Park (花やしき) this week. Hanayashiki is the oldest amusement park in Japan, located in Asakusa. Its admission fee is 1000 yen ($9.71 € 7.09) for adults, 500 yen ($4.85 €3.55) for kids. You have to pay extra fee to enjoy atractions in addition to the admission fee. For instance, you need to pay 500 yen ($4.85 €3.55) to ride the roller coaster. 

My son enjoyed "one-minute ride cheap roller coaster". You can see it at Youtube
