>>2743839If you're not east asian, be prepared for a whole lot of racism and make sure you always have cash on hand. Foreign credit cards generally aren't accepted at all, and even if you have a JCB card, some japs will just radomly decline it. When I was living in JP, there were a few occasions where I was told that there "was no way a white could have a japanese card" and that I probably stole it.
If you're planning to camp out, be sure to bring a lot of water. The japs dump most of their trash in the mountains, so you probably don't want to drink surface water even if you have a filter. If you're near american bases, you also have to worry about them poisoning the ground water - allegedly, they don't do it on purpose, but at least in okinawa, it's telling how they have their ordnance disposal / explosive training grounds right above the water reservoirs, and then act all surprised when toxic substances from fire extinguishers are found in the drinking water all the time.
Also, the obvious thing: if you don't know japanese perfectly, bring a translator app. Japs will speak to you in Japanese - if you're not speaking Japanese. At least in my experience, if you speak Japanese, many of them will immediately switch to local accents (or ryuukyuu in OKA) and pretend they can't understand you. Not sure why they do that, but bringing out a translator is the only sure way I figured out to get around it. The most annoying thing is that you don't realize it, unless you have a japanese aquaintance with you.
>>2743899>It's like +39'c in Japan in AugustThat's bullshit. Even Okinawa rarely goes over 35°C, and generally stays aroudn 28-30°C. Src: Lived there for two years.
