If you are going to be on the plane and airport that long and trying to avoid the complication of showing up positive for the C, I hope you guys where masks. I know some western people don't believe they work but if they spent time in Japan I'm sure they'd feel differently. I won't push anyone on it, everyone is responsible for their own bodies and all that, just want to see you reach your destination with as little BS as possible. So happy for you.
If btc can help with this at all let me know man. I know it doesn't always convert to cash when you need it tho.
