My memory of (another) Namba, and Japanese delay/miscommunication, is less pleasant.
My very careful planning of a day trip from Osaka to Kyoto (or maybe Nara) via the Namba train station ground to a halt when I was told, at Namba, there was no such train from Namba. Both the language and cultural-difference limits of me and the station staff left me (with lovely spouse) wandering back out, aimless and dazed. Then, and a few times later, I did not find service staff eager to offer an alternative to a problem.
There turned out to be three stations named Namba, each for a different line. I forget how we found the correct station/line, but I know we did that on our own.
At least the trains themselves were delay-free. A few days later, when I successfully navigated us into the burbs via three trains that offered transfer times of only a couple of minutes, I felt like I had just learned surfing.
