Safety concerns emerged Monday at an amusement park in Nagoya under scrutiny for a minor crash on one ride and failure to fully secure a carriage door on its ferris wheel.
The safety mishaps occurred at Higashiyama Zoo and Botanical Gardens, where all 16 attractions have since been suspended for safety checks.
According to the park operator, the slope shooter, a small roller coaster in which cars roll down a 400-meter track, experienced a minor crash when one of the cars came to a stop on a curve and another rear-ended it. Another car then bumped into the second one. No one was injured.
On the ferris wheel, one compartment was found to have gone all the way around without its door closed. The four people inside — kindergarten pupils and high school students — were unhurt.
The mother of one child noticed the door ajar and asked two part-time employees to stop the ride, but they refused and continued to let it turn, the park said.
The wheel is 36 meters high.
Hidekazu Kawakami, a senior official of the amusement park, apologized and promised to beef up training to ensure safety.
