Ahh, you meant transportation in Osaka.
Yeah, the subway system is SO efficient. It was slightly more difficult for me because, when I arrived, I knew absolutely NO kanji characters. But thankfully, stops on the subway are announced over an intercom in English, and the main ticket booths have English listed under the location names, too. If you go too far away from the parameters city, though, there will be no more English and only Japanese.
Once you understand how it works, it’s super easy and very, very safe. Children as young as 5 take the subway to school alone.
