Hongkongers travelling in the quake-hit Japanese city of Kumamoto are offering rides to fellow visitors stranded in the area.
A travel operator also said on Wednesday that one of its tour groups from Hong Kong had initially thought their coach had crashed when the 7.1 magnitude quake shook Kyushu island on Tuesday, but they safely headed to their next destination.
The quake left at least 13 people dead and dozens of others injured or missing after part of a shopping centre and a huge chimney at a paper factory collapsed, officials said.
A tsunami advisory was also issued but lifted soon after.
Travellers from Hong Kong took to social media platform Threads in the wake of the disaster seeking help with transport or offering car rides.
One user said she had arrived in Fukuoka four days ago and was on a day trip to Kumamoto to the south when the quake hit.
