Neraex is a Japanese cryptocurrency exchange founded in 2017. During the exchange's busy periods, it was able to build a client community through hosting events. Neraex, which had done a decent job in 3-4 years and was able to maintain a typical level of client satisfaction, was closed a year ago.
According to the information I got, the exchange was subjected to a cyber attack, and the exchange's website was seized. I believe that if the site has been hacked, the assets on the exchange have most likely been taken as well. However, no matter how hard I looked, I couldn't discover any information on whether or not customers have any assets in this exchange.
Also, when I looked, the exchange's website had been entirely removed. Because there isn't enough information on the exchange on the internet, I can't recommend it as a trustworthy option.
