Fukushima stn is not so far by walk about 10 min
no slope very easy just go straight for west.

Black car is so esecially in Osaka/Kyoto black taxi a lot.
But in Japan taxi colors is not only black this is in Tokyo.

Thanks for the detail reply., It was very clear and very useful.,
I need to get one more clarification., My return flight from Itami airport is at 7.50am. Probably I need to be in the airport at 6.15am. I need to leave from Fukushima station to Itami airport to reach at 6.15am . I see the bus from Herbi Osaka to Itami airport reach at 6.35 am but I feel better to reach at 6.15am. In this case how can I reach earlier the airport ? If I take taxi from Fukushima station to Itami airport how much will be the charge?

Domestic flight check in closing limit is not so early.
If "JAL" or "ANA" before 15 min is secure check limit.

So you take 1st bus enough.

Taxi fare : around 4500Y/about 20 min
include sales tax 8% and toll road(ExpWay) fee all.
(Hotel staff knows well)
