Today, I went to an amusement park whose name is "Sumaura Koen(meaning Suma Bayfront Park)". The amusement park is so old that I found letters "Kansai New Airport" on observation deck. The airport is current Kansai International Airport. But, when an owner of the amusement park renovated the park. The airport might have been under construction.
Considering the fact that the airport was constructed more than 20 years ago, The amusement park remains as it was more than 20 years ago.
