It probably won’t help you much… But you also turn on location on HelloTalk and see who’s around NY (you can actually do this on the app). This way, you can easily see who is actively studying English and would enjoy having a language exchange partner.
Check out JKuru on meetup/ Facebook site. It’s the largest language exchange meetup in NY! You can meet Japanese people who want to learn Englishand vice versa. Hope this helps!
Japan Society is a good resource. Depending on where you live the location is a bit of a pain in the neck to get to though. It can also be expensive for both the instruction and for the events.
I take language lessons at Tenri which is in the West Village near The New School.
Tenri’s language and cultural program is completely secular, but it’s affiliated with the Tenrikyo religion.
