Lightning Stops Osaka Wheel, Leaving About 20 Riders Stranded for Nine Hours

Overnight rescue ends without injuries at Expocity

About 20 people spent hours suspended in nine gondolas after the 123 meter Osaka Wheel at Expocity in Suita City stopped during a thunderstorm shortly before 6 p.m. on Tuesday. The last passenger reached the ground at around 2:40 a.m. on Wednesday, roughly nine hours after the emergency stop. No injuries were recorded.

Staff began bringing passengers down by manually rotating the wheel, moving occupied cabins toward the boarding platform. Firefighters and other emergency crews later joined the operation with specialized equipment, including a ladder truck that could reach cabins whose passengers could not quickly be brought to the platform.

The operator believes lightning interrupted the commercial electricity supply to the attraction, triggering an automatic stop. External power returned soon afterward, but the wheel's own power management and control system reportedly failed, preventing normal operation from resuming.

Osaka Wheel, billed as Japan's tallest Ferris wheel, has 72 enclosed gondolas. During the stoppage, their heating and cooling systems were unavailable, according to the operator. Riders remained inside while staff and rescuers worked through a slow evacuation amid lingering storms and winds.

As of December 3, 2025, the wheel remains closed after sustaining meaningful damage in the storm. The operator is investigating the cause and reviewing the emergency procedures used during the rescue. A reopening date has not been set.

How the rescue unfolded

Facility staff began the manual recovery after the wheel stopped. Their first approach was to turn it gradually so that each occupied gondola could reach the platform, allowing passengers to leave through the usual boarding area.

Several gondolas reached the platform during the early part of the evening. Hours into the operation, firefighters and other emergency crews arrived to help. About a dozen people were still aloft when a ladder truck was positioned to reach cabins that could not be brought down quickly through rotation.

The operation continued through the night, combining movement of the wheel with access by ladder. The main stages were:

• Shortly before 6 p.m. Tuesday: The wheel made an emergency stop during a thunderstorm over northern Osaka, leaving about 20 riders in nine gondolas.
• Early Tuesday evening: Staff manually rotated the wheel and returned several occupied gondolas to the platform.
• Hours into the rescue: Firefighters and other emergency crews joined the effort, with about a dozen passengers still waiting above ground.
• Around 2:40 a.m. Wednesday: The final passenger reached the ground, ending the evacuation roughly nine hours after the stop.

Manual rotation is a standard recovery procedure when a ride stops and its power systems cannot immediately return to normal. It is slow by design: crews need to avoid sudden movements and limit risks to people inside the cabins.

Why restored electricity did not restart the wheel

The operator's preliminary explanation involves two stages. First, a lightning linked interruption affected the commercial power feeding the ride. The loss of that supply triggered the automatic stop. Second, after external electricity returned, a fault in the wheel's own power management and control equipment reportedly kept the ride from restarting.

A return of grid electricity does not automatically restore every piece of equipment connected to it. A surge, meaning a sudden rise in electrical voltage, or a brief power loss can cause equipment farther along the electrical system to shut down.

The wheel's controller coordinates motors, brakes and cabin systems. If that controller develops a fault, technicians may be unable to issue the commands needed to restart the ride. Crews must then rely on manual procedures or equipment that lets firefighters reach passengers directly.

Investigators are examining whether lightning struck the wheel directly or whether an electrical surge reached it through nearby lines or paths through the ground. They will also examine why the controller did not permit a restart after the commercial supply returned.

What the safety systems are designed to do

Amusement rides are designed to move into a safe condition when sensors detect faults, electrical spikes or other irregularities. On a large Ferris wheel, brakes stop rotation. The immediate priority is to stop movement while the system checks whether operation can safely resume.

Gondola doors remain locked unless a cabin is at the platform and an authorized release takes place. The control room also prevents a restart until checks confirm stable electricity, working communications and correct readings from sensors.

Those layers of protection explain why an electrical problem can leave a wheel stationary even after power is available again. Motors, brakes, communications and sensors all need to work together before normal movement can resume.

Tall attractions of this scale are typically fitted with lightning protection and grounding. These systems give electrical energy a route away from people and into the ground, reducing risk during a strike. Sensitive electronics can still stop working during a violent storm.

After a suspected lightning strike, operators commonly inspect cables, control cabinets and safety devices before allowing a ride to operate again. The electrical checks are part of determining whether the systems responsible for movement and stopping are ready to work together.

Hours of waiting inside enclosed cabins

Osaka Wheel's cabins normally have heating and cooling, but those systems were unavailable during the outage, the operator said. Passengers had the shelter of the gondola shell and periodic updates from staff while the evacuation progressed.

Winds at the height of the wheel can cause cabins to sway slightly. That movement can add to passengers' discomfort even when the structure is not in danger. A long wait without temperature control or bathrooms can also be stressful, especially for families with children and older visitors.

Rescuers prioritized safety checks and communication while bringing people down. Some passengers left after their gondolas reached the platform; others needed assistance from the ladder truck because their cabins could not easily be aligned with the boarding area.

The deliberate pace traded speed for control, an approach commonly used in aerial rescues involving weather and high structures. All passengers eventually reached the ground without recorded injuries, although the wait continued well into Wednesday morning.

Staff and firefighters combined two rescue methods

Expocity staff coordinated with fire authorities to stage equipment, prepare the platform and guide riders down step by step. Firefighters reported that staff had already rescued a number of passengers by the time they joined the operation.

A ladder truck needs careful positioning and sufficient clearance, particularly in gusty conditions. Crews alternated between mechanical rotation and access by ladder according to which method was safer for each gondola.

For cabins reached from outside, firefighters used a telescoping ladder to get to the doors, secure passengers and escort them down. The ladder can extend to reach elevated places, but the vehicle and ladder must be positioned carefully before anyone transfers out of a cabin.

Training for rescues at height and platform operations is routine for urban fire departments. The operation at Expocity proceeded at a calm, steady pace as staff and emergency crews worked through the remaining occupied cabins.

The wheel's scale helps explain the length of the recovery. An attraction standing 123 meters tall offers wide views when it is running, but moving cabins into a safe exit position takes time when its normal systems have stopped working.

Damage checks before a return to service

The wheel remains closed for inspection and repairs following the storm damage. After an event of this kind, operators typically inspect the structure, drive and brake systems, and control electronics from top to bottom. Components affected by a surge are repaired or replaced.

Authorities may also review maintenance logs and approve a plan for returning the attraction to service. The operator has said it is investigating the cause and reviewing the emergency procedures used on Tuesday night and Wednesday morning.

Before the ride returns, technicians will verify cables, bearings, sensor networks and the power management units that coordinate the system. Bearings support moving parts, while the sensor network provides information that helps the controls manage the wheel safely.

Test runs with empty cabins usually take place before a limited reopening. Staff remain ready to monitor the circuits during that stage, checking the ride's operation before passengers return.

The repair work and the review of the rescue address different parts of the incident. Technicians need to restore reliable operation, while managers need to examine how passengers were supported and brought down during the prolonged stop.

What the investigation will examine

Technical teams will map the sequence from the first electrical disturbance to the final evacuation. Their preliminary focus is the lightning linked failure of commercial power followed by the fault in the wheel's own power management system.

Engineers will examine both possible routes for the electrical disturbance: a direct strike and a surge transmitted through nearby lines or the ground. They will also check the controller's response when the external supply returned.

Managers will review the manual rotation procedures and the calls made to passengers waiting in the cabins. Fire crews' use of a ladder truck to reach higher cabins will form another part of the assessment.

The review will consider whether more backup power at the site, temporary lighting or additional portable equipment for temperature control could make a prolonged wait easier for passengers during future storms. Managers will also examine whether changes to software logic, surge protection or training could shorten rescue times without adding risk.

Those areas of review connect the equipment failure with the experience of the people inside the cabins. Restoring movement is one concern; maintaining communication and passenger comfort during a lengthy recovery is another.

What visitors should know about the closure

Osaka Wheel is inside Expocity, a shopping and entertainment complex in Suita City. It stands beside the Tower of the Sun, the landmark sculpture preserved from the 1970 Japan World Exposition.

The attraction is marketed as the tallest Ferris wheel in Japan. Its 72 gondolas include premium cabins, and it normally operates throughout the year when weather permits. On clear days, passengers can look across the northern Osaka plain, a view that attracts visitors from Japan and abroad.

Visitors planning a trip to Expocity should check the wheel's operating status before travelling. Nearby dining and shopping facilities and the Expo Commemoration Park remain open on their normal schedules, weather permitting.

Ticket policies during ride closures are handled by the operator at the point of sale. Staff at the site usually guide customers on refunds or rebooking once operations resume.

Thunderstorms occur most often in summer, but they can also develop at other times of year. Parks and attractions in Japan suspend rides when lightning is nearby. Stopping operation is a standard industry safety practice and was part of the protective response during this incident, which ended without injuries.
