I usually stay away from participating in conspiracy theories thrown around in this thread, but I think she is actually in Japan.
1. She posted those stories about 12-13 hours ago in broad daylight.
This means that she couldn't possibly be in Brazil because I believe at that hour it would the middle of the night.
2. She did mention in her OF stream that she had travel plans, and she would not be able to film ASMR videos.
Taking a trip to Japan and having to bring equipment to record videos sounds like a pain in the ass, hence why this might be the trip she mentioned.
Then again, maybe we are just schizos.
