Kickstart Your Journey with a Generous Welcome Bonus

At KoiFortune Casino, we warmly welcome new users with one of the most valuable welcome packages in the industry—up to ¥300,000 plus 200 free spins to get you started in style.

What is the Welcome Bonus?

The Welcome Bonus is a special offer for new players who register with KoiFortune Casino and make their first deposit. The welcome package is divided into three tiers based on your deposit amount.
The most luxurious sign-up bonus is available for deposits of ¥300,000 or more. This 100% match bonus allows you to receive up to ¥300,000 extra. For example, if you deposit ¥300,000, you’ll receive another ¥300,000 as bonus funds—starting your casino journey with a massive total of ¥600,000. The wagering requirement is 30x, with a payout cap of 10x the deposit amount.

How to Claim

Receiving bonus funds at Koifortune Casino is very simple. First, visit the official website and create a new account. Just enter your email address, password, and basic personal information, and the registration will be completed within minutes.
After creating your account, go to the “Deposit” section. Here, select your initial deposit amount — the minimum deposit is ¥3,000. Choose your preferred deposit method, enter the amount, and make sure to select the “Welcome Bonus” option.
If you skip this step, the bonus may not be applied.

Important Terms and Conditions

To make the most of the Welcome Bonus, it’s essential to understand a few important terms. First, the bonus validity period is set to an exceptionally long 300 days, meaning there’s no need to rush — you can enjoy the games at your own pace. Compared to the typical 7- or 30-day limits seen at other casinos, this is an incredibly generous condition.

Before meeting the wagering requirements, there is a maximum bet limit per spin or game round. This is generally set at around 10% of the bonus amount. Also, not all games contribute equally toward fulfilling wagering requirements. Slot games usually contribute 100%, whereas table games and live casino games contribute at lower rates.

When making your first deposit, you can choose one of three special welcome options. One option includes free spins on the popular slot game Sweet Bonanza, with 20 free spins per day for 10 days, totaling 200 free spins. Winnings from these free spins are subject to a 41x wagering requirement.

Boost Your Balance with Weekly Reload Bonuses

At Koifortune Casino, we don’t just reward new players. We also offer regular reload bonuses to give continuous value to repeat players. These bonuses apply when existing users make additional deposits and act as deposit matches to effectively boost your gaming funds.

Weekly Reload Offers

Koifortune Casino provides different weekly rewards based on the day of the week. One of the most popular is the Wednesday Reload Bonus, where players receive a 50% bonus on deposits made that day. You can receive up to ¥30,000, making it a perfect midweek bankroll booster.

There are also special weekend reload bonuses. On Fridays, a high-yield 75% reload bonus is offered, allowing players to receive up to ¥20,000. This is a great opportunity to increase your balance ahead of long weekend play sessions.

Special Reload Promotions

In addition to standard weekly reload bonuses, Koifortune Casino also runs holiday promotions tailored to seasonal events and Japanese holidays. These limited-time offers typically come with better terms than regular reloads, offering greater bonus funds and more free spins.

Since these special reload promotions provide more value than the usual ones, it’s important not to miss them. Be sure to check the Koifortune Casino website and your email newsletters regularly to stay updated and make the most of these exclusive deals.

Big Wins with Free Spins

At Koifortune Casino, we offer a range of free spin promotions designed to provide slot enthusiasts with a unique experience. Free spins allow you to enjoy slot games without wagering your own funds, giving you a risk-free chance to win real money.

Our free spin promotions are among the best in the industry in terms of frequency and value. In addition to regular offers, we also feature jackpot slot showcases and special event-based free spins for even more excitement.

Free Spin Details

Koifortune Casino offers scheduled free spin promotions on specific weekdays. Every Thursday is “Spins Day”, when players who deposit ¥5,000 or more receive 50 free spins. These spins are valid on selected popular slots and must typically be activated within 24 hours.
Winnings from free spins usually come with relatively low wagering requirements (around x30–x40), making them easier to convert into real cash. This lets you enjoy slots daily with a fresh thrill.

Slot-Specific Promotions

In addition to free spins, Koifortune Casino regularly holds special promotions for selected trending games. These events add excitement to your regular gameplay and often come with exclusive bonuses and prize opportunities.

Loyalty Rewards & VIP Benefits

At Koifortune Casino, we express our appreciation to dedicated players through our loyalty program. The more you play, the more benefits and rewards you receive. This system is designed to enhance the experience of long-term players with meaningful, progressive perks.

As a VIP member, you gain access to custom bonuses, personalized support, and invitations to exclusive events — privileges not available to regular players. The VIP program delivers an elevated experience, ideal for serious players and high rollers alike.

Loyalty Point System

The foundation of Koifortune Casino’s VIP program is the loyalty point system. Points are awarded based on real-money bets, with the rate depending on the type of game.

Slot Games: Highest point return. You receive 10 points per ¥1,000 wagered. This makes it easy to climb VIP tiers efficiently by playing high-RTP slots.

Table Games: Points vary by game type, typically 5 points per ¥1,000 wagered. Even in strategic games like blackjack or roulette, you can steadily accumulate points.

Live Casino Games: Earn points while enjoying a realistic experience — 7 points per ¥1,000 wagered. Face professional dealers and boost your VIP status simultaneously.

VIP Tiers and Rewards

Koifortune Casino’s VIP program is divided into five tiers, each offering exclusive benefits based on player activity. As your level increases, so does the value of your rewards.

The highest tier, Diamond, is reserved for the most active players. Benefits include a 20% weekly cashback, access to exclusive VIP events, and luxury travel invitations, providing a true VIP lifestyle.

VIP tier levels are automatically adjusted based on your activity over the past 30 days and loyalty points earned. Once you reach a high tier, it’s important to keep playing regularly to maintain your status.

Receive Weekly Cashback!

At Koifortune Casino, we’re committed to delivering value regardless of whether you win or lose. That’s why we offer generous cashback bonuses. Just like in any casino experience, there are winning days and losing days. Cashback is a key feature that helps reduce the sting of losses by giving you a percentage of your lost funds back.

How Cashback Works

Koifortune Casino’s cashback is calculated based on your weekly net losses. Net loss is defined as the total amount deposited during the week minus the total amount withdrawn.

The standout feature of our cashback program is the low wagering requirement. While most bonus funds come with a 25x–30x wagering condition, cashback bonuses are subject to just a 5x requirement. This makes it much easier to convert cashback into real, withdrawable funds.

How to Receive Your Cashback

Claiming your weekly cashback at Koifortune Casino is simple. Just log in to your account every Monday — the start of a new week — when cashback from the previous week is calculated and made available for use.

Exciting Tournaments with Big Wins!

In addition to regular gameplay, Koifortune Casino frequently hosts exciting tournaments. These competitions add a thrilling, competitive edge to your experience and offer a unique opportunity to win big rewards outside of standard play.

Ongoing Tournaments

Koifortune Casino runs various leaderboard challenges on a regular basis. One of the most popular events is the Weekend Slot Battle, held every Friday through Sunday. With a prize pool of ¥1,000,000, rewards are distributed among the top 100 players.
To participate, simply play the specified slot games — no registration required. You’ll be automatically entered onto the leaderboard.

How to Join

Joining a Koifortune slot competition is very easy. Just go to the “Tournaments” or “Competitions” section in the main menu of the website. There you can view all current and upcoming tournaments at a glance.

Don’t Miss Out on Limited-Time Offers!

At Koifortune Casino, we run a variety of limited-time offers throughout the year. These exclusive promotions are tied to specific seasons, holidays, or sporting events, offering players an opportunity to enjoy more attractive perks than regular bonuses or promotions.

What makes limited-time promotions so appealing is their uniqueness and high value. They often come with higher bonus rates, lower wagering requirements, or unique rewards. Taking advantage of these special opportunities is a great way to maximize your casino experience.

Special Events

Koifortune Casino regularly offers seasonal bonuses inspired by Japanese culture and calendar events. Be sure to check the official website often to stay updated.

Promo Codes

Koifortune Casino is planning to introduce exclusive deals using promotion codes. While there are no active codes at the moment, new ones are expected soon.

Play Responsibly

At Koifortune Casino, we prioritize providing players with a safe and enjoyable responsible gambling experience.

We are committed to supporting responsible gaming by encouraging players to recognize their limits and play safely.

We also provide self-exclusion tools for those who need them.
