Which airport should I use for the Kansai area?

The difference is the size of the airports and whether they provide domestic or international service. Osaka airport (aka Itami Airport) and Kobe Airport are domestic only airports while Kansas International Airport (KIX) is domestic and international. Which airport you want to use depends on your schedule. As Kobe and Osaka airports are small in comparison to KIX, the number of flights is limited. But if you're going to visit Kobe first, Kobe airport is closer, and if you're going to visit northern Osaka first, Osaka Airport is closer. So take a look at the flight schedule and your itinerary and choose which airport to use.

I am a big fan of J-rock music and thus decided to visit Japan this July in order to get acquainted with the country and also to visit the concert of my favorite band. I decided to order tickets https://www.iflyfirstclass.com/city/to-tokyo-hnd and I did not regret about my decision. Manager helped me to choose the optimal flight plan, answered all my questions and helped with the order. I was very happy with the trip and I think I will go to Japan again in the nearest future.
