Small edit - I meant to say marketing is more science than art. Definitely need creativity in ad campaigns, but like a good movie, there needs to be a solid plot and message to serve as the foundation.
Instagram is still wrongly focusing on the channel instead of audience. For example, if the buyers are younger people into fashion and food, and there are relevant profiles that showcase both, perhaps while traveling to Japan and showing how you can get the same candy at home, that might be effective. But you need the data to show that, not just assumptions.
Search is always a great way to advertise because you can target directly to people's intent as they type it in. Buying a few keywords around candy, japan, snacks, traveling, etc. is a good and affordable way to start. $5K spend on some ad strategies would provide decent data to start testing the market.
