There's an expectation that you'd participate at least to some extent. There will be smaller karaoke / drinking type parties after work, and a larger 'nomikai' meal at a large restaurant which is used to celebrate a major milestone say every month or quarter.
You would probably be expected to participate in the larger one, whereas particpating in less of the smaller ones would become adverse career wise over time. Drinking is theoretically optional.
Typically family time seemed to be at weekends, and heavily focused on getting out and about into the countryside etc. The apartments are so small that it wouldn't really be feasible or desirable to hang out at home much.
