A Spring Japan flight from Shanghai to Tokyo made an emergency landing in Osaka on Monday (June 30) after a cabin depressurization warning. Photos and videos shared on Xiaohongshu, a Chinese social media platform, showed oxygen masks hanging from the cabin ceiling of flight JL8696/IJ004. One passenger reported hearing a loud "boom" just before the masks were released, followed by a flight attendant urging everyone to put them on.

Passengers were told to fasten their seat belts, and the captain announced an emergency landing. Another traveller mentioned that the cabin lights dimmed and the air grew warmer during the incident. Around 15 minutes later, the captain reportedly informed passengers they could remove their masks, and the plane landed safely in Osaka about 30 minutes after the situation began.

According to Kyodo News, the aircraft touched down at Kansai Airport at approximately 8:50 p.m. with 191 people on board. No injuries or illnesses were reported. The outlet also noted that the incident was due to a loss of cabin pressure. Spring Japan later issued cancellation certificates to passengers, citing a mechanical issue as the reason for the diversion. An investigation is currently underway.
