From kansai airport to mamba after 2400?

Flight scheduled to arrive 2225. Other than taxi what mode of transport, bus or train, would be available to go to Osaka central after 2400? Thanks.

You may be able to catch the last train around 23:30. Afterwards, there are neither buses nor trains. In any case, I recommend to spend the first night at the airport:

Afterwards, there are neither buses nor trains.

There is one bus leaving KIX for Namba at 0:15 or 0:30 depending on the terminal.

I stand corrected.

No worry if your flight no delay and very strong wind.
Really bad weather make all transport stops long sea bridge
railway stop first then car road.

(note)
Town name is "N"amba (not "M"amba).
