There seem to be a lot of Japanese phrases that are used very widely. I'm finding it hard to get a cross cultural/language handle on this. For instance in Aikido, it seems like "Onegaishimasu", "Hai", "Osu" are used a lot in a lot of very different situations.
I'm not sure if this question makes sense, but are there equivalent English / American phrases that would be similarly used? I'm just trying to get a gut level comparison that my mind can wrap itself around...
