Sorry to hear about your experience Kaos. Dont want to go into too much detail but we encountered the same sh%t. My wife was rushed to hospital via ambulance & spent the next 6 hours in intensive care, CT scans you name it. She remembers our group of friends walking to the bar, talking to people & having a couple of drinks. About 30-40 min after arriving she collapsed pretty much completely unresponsive, she has no memory of the events between arriving at the bar & waking up in intensive care. The only thing she remembers is me yelling her name while trying to keep her conciouse until the ambulance arrived. They were 6 of the longest hours of my life, doctors not able to tell me for 4 of those hours if she was going to be ok & having to sign all sorts of concent for many proceedures. She also spent the next 24hr violently ill. The medical certificate states Acute medical poisoning. This is real people & it is not isolated to the city, this happened at a popular JP ski destination. After many years travelling to Japan we had never even heard of this happening, let alone experienced it. Its true our guard was down, but with the influx of foreign tourist's and the current situations its now well and truely up. Needless to say all of our Japanese friends & family are completely horrified that this is now happening.
cheers
