Proposal from Japanese friend: What exactly is this?

Apologies if this is the incorrect sub or if this is a stupid question. I also apologize for the vague title, I didn't know how to describe things. Anyway, I've had a Japanese friend for a few years that I've played games with off and on. They've been cool to hang out with. I'm in the US and they were in Japan, at least when I met them. Recently, they sent me a message saying that their boss wants to purchase American goods, send them to my address and have me send them to Japan. My suspicion is that they're trying to avoid tariffs and I'm wary of the legality of that. I requested a company name and my friend named an online Japanese storefront that is apparently legit, according to a post I found on this sub, but I'm frankly still not quite clear on what my friend's work arrangement is. The act of writing this out has made it sound even more suspicious to me. Would anyone have any insight on what this actually is?
