There's no doubt in my mind that JapanCupid.com is indeed authentic. Now with being said, there are indeed scammers that prowl this website. Then there's a matter of member having expectations high in excess.
Trying to get an actual Japanese girl to respond is a massive chore, that is unless you are extremely handsome, rich, highly educated, and either planning a trip to Japan or living there. I would not recommend JapanCupid.com if you don't plan on going to Japan in the near future or live there.
My next issue is exclusively for Chinese members who use this site. It seems a great a deal of them make contact with you to exchange emails and eventually con unsuspecting men onto a website called Fatemeet.com. This website is all pay to do anything, including communication, don't fall for it. I recommend if someone from China does contact you, make it clear that you will not use Fatemeet.com.
Then we have people from Ghana or some other place in Africa posing as someone they clearly are not. The most experience I have is someone asking for funds to buy a phone so they could take pictures to send to me. Yeah...
Again, I do believe the JapanCupid.com and its affiliated sites are indeed real, however, they are ripe with scammers. Then of course you have people signing up simply out of curiosity who have no plans to tie the knot with a foreigner.
My advice, keep your expectations low unless you plan on going to Japan or already live there. Also, pay close attention to detail in how people respond to you. Allot of times a scammer won't read your profile or even read questions to ask, it's a dead give away. Pictures, scammers will use pictures of extremely gorgeous women, watch out for that too.
If you know the local language, that too would be an added bonus in your effort to find someone, not many members have a great command of the English language. Other than that, yeah the site is real with real members, but it's just shy of being a lost cause if you plan to find love, however, that's with any sort of online dating, if you're a guy the odds are definitely NOT in your favor.
I want to add that I am not some disgruntled member. This is all based on my unbiased observations, I have made contact with some members, but I signed up with low expectations to begin with.
Pros
It's real and there are real people to chat with if you can find them.
Cons
There's enough cons that I'd suggest meeting women in real life as opposed to attempting online dating. Note: you will have to pay to utilize messaging on JapanCupid.com and any of its affiliated sites. Quite frankly it's not worth it.
I joined recently so it may be too early to review, however, with that being said, I can review a few things with confidence.
1. There are gold farmers on JC, most seem to be Chinese in origin. Usually they will try to get your email and after a few email conversations they will try to get you to sign up on fatemeet and some other site.
2. It is VERY hard to get a response. People, keep your expectations LOW, or you will easily be crushed. For me it doesn't matter if anything comes of JC or not. The fact of the matter is JC like any other form of online dating can be super unforgiving.
3. The site is fairly simple and easy to navigate. Naturally it helps to be a paying member. I paid for a full membership, either way women will cost money at some point.
4. Again keep your expectations LOW, and I mean VERY LOW!
I personally can say with 100% confidence that I will not be finding a Japanese girl here, but that's the reality of online dating. Your milage may vary, good luck!
Pros
Simple
Cons
Beware of fakes and gold farmers.
Review: Pros and Cons
Even with a subtle approach, your mileage may vary. As I mentioned in my own review, there seems to be gold farmers trying to get unsuspecting members onto other sites that cost to communicate. It's much the same way as JC, you pay to communicate, but why on earth would you migrate to another site to pay and communicate there, when you already paid JC to be able to send messages. Something seems afoul, but I don't think JC is behind it.
No one ever said finding the special would be easy lol
