We can still see some differences between the two countries. One is that Moto has a problem using first names for people he doesn’t know very well. Moto would like to know the background but for Kubushevsky and his boss it’s not very important.
In japanese culture the person in a lower position is the one that has to pour the drinks. This can be seen when Moto pours a drink for Kubushevsky which is normally the role for a junior (when Kubushevsky shows Moto around he takes on the senior position).
