what do you mean by travelling around? 5 days in Osaka or 5 days for the Kansai region? The best known towns in the Kansai are Osaka, Kyoto, Nara, Kobe. They are very close to one another and there are numerous commuter trains between these cities (and others) all day long. I mostly use JR as it goes everywhere but you can also use other rail companies. Check Transportation then trains passes on this site under A-Z at the very top of the page.Be sure to check www.osaka-info.jp/en/ for tons of info about Osaka.

5 Days is a lot of time, do you plan to stay in Osaka or travel to other Kansai areas?
In Osaka, I reccomend going to Osaka Castle and Dotonburi. Also a day trip to Nara is well worth it. Havent been to Kyoto yet, but I have read wonderful things about it. Let us know what you are interested in.

Actually there is much more than Dotombori and the castle! Kita Umeda and Minami Namba each have lots of great stores, thousands of restaurants,interesting buildings etc. There are also old shrines like Sumiyoshi taisha and the trendy areas of Orange street and Amerika mura and much more. There is indeed enough for 5 days. Check it out on www.osaka-info.jp/en/ All the same I would suggest to visit Nara, Himeji castle(bigger than Osaka's and the real thing, not a replica)and of course one should also explore Kyoto for 2 days at least. the OP hasn't replied so we can't help re transportation but suffice to say that there are several local passes that can cut down on expenses if wisely used. Check rail passes under transportation in the A-Z section at the very top of this site.

Osaka is a good base for visiting Koya-san which is about 90 min by train from Nankai Namba Station.
