Hot pots are great. We call them nabe in Japan and are a staple dinner in winter. Much of the same ingredients you used but also various types of fish cakes. I prefer pork and always douse my own bowl in ponzu.
There is some communal/family aspect to it as well as slowly eating, cooking and chatting. Everyone should try it.
I'm more familiar with shabu shabu because it's more like the hotpot we normally eat. Either way, they're great meals.
Ponzu is much nicer because soy sauce is too salty unless I water it down, then it losses its flavour. Maybe I'll get some ponzu instead in future. The Japanese fishcakes are very nice, and pretty!!!
