The Japanese online casino review site

In this article we are going to review one of the biggest Japanese online casino review sites. The website is called They are relatively new and have only been operating for about 6 months but have already gained a lot in popularity. Their main focus is great responsive design plus good content. As you may be aware of most Japanese people stuf the Internet using their phone or tablet. At the moment there isn’t any other responsive online casino review site for Japanese people except Manekinekocasino and 1-2 others.

They also provide their readers with the most relevant and important information when it comes to gambling in Japan and where people who seek to gamble online should turn to. There are only a few online casinos that accept Japanese players and Manekinekocasino have listed the top ones.


Mobile adapted design

As written above almost all young people in Japan are using their mobile phones to surf the web. Therefore it’s absolutely crucial that the websites are made with responsive design. Manekinekocasino have thought of this and if you enter their web site from your iPhone or android phone you can see it very clearly. We were actually a bit surprised that there are so few casino review sites that offer this.


Very detailed reviews

So they’ve got the design. What about the content? Just like the design the content is very well thought through. When you arrive to the web site you are faced with an introduction. You can read about casino bonuses, live casino and the top three online casinos for Japanese gamblers. These are

Vera&John casino. This is a scandinavian online casino that they rank as nr 1. Read the review here:

The second best casino they recommend for Japanese gamblers is Intercasino which is the oldest online casino in the world. Read the review here:

Last but not the least we have William Hill casino that is a brittish online casino. They offer all the casino games from Playtech plus an excellent live casino. Read the review here:




One of the best and most informative online casino review sites that targets Japanese visitors. Great content and design. They also have some exklusive offers that are only valid if you register through their web site so definitely check that out. We give this review site 9.5 out of 10 stars. The only thing we are missing are some more reviews but that should come eventually.


Review of Gamblingmetropolis


The best casino bonuses and free spins promotions

Today we are going to review Gamblingmetropolis is a review site that writes about different online casinos. They have made an excellent effort in becoming one of the biggest casino bonus sites for European gamblers. What sets Gamblingmetropolis apart from other review sites is their good design and easy overview. For a new visitor it’s very easy to find the best casino bonuses.

Different kinds of bonuses

Gamblingmetropolis offer their visitors two kinds of bonuses.

Deposit bonuses: The front page covers all deposit bonuses. These are bonuses that require a deposit from the player. The most common bonus is 100% up to €100 but they have also listed some top quality casino bonuses that gives triple the money up to €300.

Free spins/free money bonuses: The other page displays all no deposit bonuses. These are free bonuses that don’t require a deposit. Some casinos offer new registered players free spins or free money in order for them to create an account. One example is one of their listed casinos Prime Slots. They offer €5 for free to all new registered players. All it takes is to go through the link at Gamblingmetropolis and open an account. The free money is credited instantly.

Detailed instructions for every bonus

One thing that almost every single review site fails on is that there are no instructions on how to claim the bonuses. Often they will just mention that the player can receive a 100% up to €100 bonus but it doesn’t mention if the player has to accept the bonus prior to deposit, if it’s credited automatically or if customer service has to credit it manually.

At every single bonus review provides perfectly detailed instructions on how to receive the different promotions. This saves a ton of time for the player.


Updated offers

Another mistake that a lot of review sites will make is that they don’t keep their offers updated. As a player you can feel really tricked as some web sites will list offers that has expired. This happens often when the web site in question promotes a no deposit offer that is no longer active.

The good thing about Gambling Metroplois is that they always update their offers. They seem to have a large amount of people that stay on top of each offer, making sure that it’s updated and that the offers are active. They also list each country’s bonuses as an offer that’s valid for players from United Kingdom might not necessary be valid for a player from Austria or Switzerland.


Bonus features

They provide an excellent blog where the latest casino promotinos are presented in a nicely fashion. Usually they will update this blog a couple of times a week so it pays off to bookmark the page. Other good pages on the site is their casino games page. Right now they have a section about video slots from WMS (Williams Interactive). These video slots are absolutely amazing and have only been available to land based casinos before but now one can finally play them online. You can read more about this section at

This is one of the most famous WMS video slots

Bruce Lee video slot from WMS



All in all we give this website 10/10 stars. The layout is easy to understand and navigate. Best offers are listed at the top for easy access. The reviews of the different online casinos provide important information. One of the best features is the instructions on how to claim each bonus. All promotions are contstantly updated.
