Date/experience ideas?

My partner lives in Okinawa while I am overseas, I’m visiting him in mid Jan-mid Feb and his birthday is coming up soon. I wanted to get him an experience we can do together while I’m there to make memories. I was thinking a whale watching tour but he gets pretty seasick so nothing with boats unfortunately. I was thinking a budget of $100-$150 per person. Any suggestions?
