I've searched all over Japanese news for the past month on this and for some reason I don't see anything on ivermectin's recommendation. I only found reports saying it's not proven, and still waiting on the trials at Kitasato. I'm baffled. Where do you see official announcements?
Hey I like you and your effort to find and share protocol. For Tokyo case, it is unlikely it’s IVM.
Some people import for their own safety, but it is considered dangerous attempt in most of people and IVM is never be popular at this point in Japan.
