Namba railway and Den-den town

Hi is Namba station, Namba(subway) and Osaka-namba station just next to each other?

May I know where is the nearest station to Den-den town (Osaka)?

Thanks

Well, this might be a bit complicated, since it's a big station (or stations? ^_^) It depends if you arrive by JR, Nankai, or subway.. If you go by subway, you can get off at exit 17 (I guess.. ^_^) and go to the east (past Bic Camera store) and you're basically there.. or you can get there underground.. (Namba Walk to Nipponbashi station) Den Den Town (Nipponbashi) is the area centered along Sakaisuji street.. (between Nipponbashi and Ebisucho stations)
