Looking for advice on my video idea (talking to travelers in Tokyo)

Hi everyone!
I’m Shun, a high school student from Japan.

I’m planning to create videos where I talk to travelers or international students visiting Japan — mainly in places like Shibuya.
I studied in Los Angeles for one month this summer, so I can speak a bit of English. I don’t want it to be just English practice content. Ideally, I want to walk around together, show them cool spots, and maybe eat ramen or other food with them while filming.

But I really don’t want to bother tourists or make them uncomfortable.

So I’d love to hear your advice:

What’s the best way to approach travelers politely?

What should be the first thing I say to them?

As visitors to Japan, what kind of approach would make you feel comfortable talking to a stranger filming a vlog?

Any thoughts or advice would really help! Thanks!
