What to Look for in a Casino Bonus in Japan

From the outside, bonuses seem like great offers that reward you for making deposits to the casino. But when you start delving into the details, you realize there’s more to it than meets the eye. This is why it’s important to have a basic understanding of casino bonuses.

When considering casino bonuses in Japan, you need to start by understanding the exact nature of the offer. There are different promotional offers, some of which might even ask for a bonus code. Some of the popular casino bonuses are:

  1. Welcome bonus.
  2. Deposit bonus.
  3. No deposit bonus.
  4. Free spins bonus.
  5. Reload Bonus.
  6. Live Casino Bonus.
  7. VIP Bonus.

Each of these offers comes with its own sets of terms and conditions. Before claiming these offers, please set aside some time to read the terms and conditions of the offer to learn more about it. You can find any information about the offer in the T&Cs section.

While it’s not necessary to remember every little detail, you should try to remember a couple. Look for the minimum deposit amount, expiration date, and wagering requirements, as you’ll need them if you try to withdraw the bonus offer.

Activating Casino Bonuses in Four Simple Steps

You might have thought that using a slots bonus offer might be harder than playing the game itself. However, that’s not the case at all. Activating bonuses on Japanese casino sites is easier than you think.

Whether claiming casino bonuses for slot machines or any other game, you can activate the offers in four simple steps. Check it out.

  • Choose a Reputed Online Casino for Registration
    step 1

    The first step to activating casino bonuses in Tokyo requires you to be signed up as a member of the online site. However, if you don’t want to switch to a new casino in one month, you must choose the right one.
    There are several factors that you need to think about when picking out the perfect casino for you. Check to see if it’s licensed to offer its services or not. You should also make sure it offers games that you’ll enjoy playing.
    And don’t forget to check the supported payment methods for smooth transactions.
    If choosing a casino by yourself feels too much, you can always check online reviews and recommendations like the ones we offer. You can rest assured knowing you’ll find the top websites with the best casino offers.

  • Go Through the Terms and Conditions
    step 2

    As we’ve mentioned before, you need to take some time to read the terms and conditions of the casino bonuses in Japan. Choose any bonus that you’d like from the “Promotions” page and read its terms.
    For new players, we recommend that you start with the welcome bonus. That is undoubtedly the best bonus you’ll get at any online casino. Find out all the finer details about the offer before proceeding to the next step.

  • Deposit the Required Amount
    step 3

    If you want to activate the bonus offer immediately, you need to make the qualifying deposit. Sometimes, you might need to enter a bonus code when placing your first deposit. But if there’s no mention in the terms, you can simply make the minimum deposit to be eligible for the bonus offer.
    Here’s some wisdom that might come in handy when making your deposit. Check the terms to find the maximum bonus amount you can get. If it’s a 100% deposit bonus for up to ¥50,000, you shouldn’t deposit more than ¥50,000 as that will let you enjoy the maximum bonus.

  • Enjoy the Bonus
    step 4

    Once you’ve gone through the steps mentioned above, all you can do is enjoy the bonus. The system is designed so that you get the bonus added to your account in the shortest possible time. You’re now free to use the bonus funds any way you want.

Best Types of Casino Bonuses

Type of Bonus


Welcome bonus

This casino offer is exclusive for first-timers. Only players who’ve signed up with a new account can receive the bonus.

Deposit bonus

As regular players also deserve bonuses, the operator offers deposit bonuses regularly. These come with bonus funds and, in some cases, with free spins.

Free spins bonus

As you might have expected, the free spins bonus offers free chances to spin the reels in slots.

Reload bonus

The reload bonus gives players who make regular deposits a reward. The bonus is a portion of their total deposit over a certain period.

No deposit bonus

The easiest offer to claim in online casinos. Players only need to complete certain conditions and objectives to enjoy this bonus.

Tournaments and special events

Slot races and live dealer tournaments are a regular occurrence at online casinos, and operators offer bonuses for those events.

VIP bonus

VIP programs offer a gamified approach to casino bonuses where players get better rewards as they level up their VIP status.

Best Kinds of Casino Bonuses for Different Types of Gambling Personalities

Japanese gamblers are incredibly versatile when it comes to personalities. There are different kinds of gamblers, each with their own goals and needs. That’s why each one requires a different kind of bonus offer.

Pros and Cons of Betting Bonuses

Pros and cons of using casino bonuses

With a casino welcome bonus, the start of a new player’s journey becomes more fun. They get a boost to their initial bankroll. This sets the stage for them to play any game that they want.

These welcome bonuses come with free spins. Typically, the operators mention the games where players can use the bonuses. This means they also get the chance to try out a completely new game.

But if this guide successfully taught you more about bonuses, you should know that all promotional offers on casino sites have a wagering requirement. Players must complete this requirement to withdraw the bonus amount as real money.

Bonuses also last for a limited time. So, this can create unnecessary pressure in the player’s mind to complete the requirements in due time.

Casino Bonuses vs. Sports Betting Bonuses

When talking about bonuses, we also need to talk about the sports betting offers. These are distinct from having similar rules because the terms of these offers are slightly different. Look at the comparison between these two types of bonuses in the table below.


Casino Bonus

Sports Betting Bonus

Welcome Bonus Rewards

Welcome bonuses for casino players are typically deposit bonuses. They can also come with free spins.

The bonus rewards for a sports betting bonus can be different things, such as bonus funds, free bets, etc.

Live Gameplay

The live gameplay element in online casinos is limited to live dealer games where players can play alongside other users accompanied by an actual human dealer.

Live betting markets allow for wagering in real time on live matches. Bettors can see the odds shifting on the live betting interface in real time.

Minimum Odds Requirement

Casino bonuses don’t need to be wagered on any specific game. You can wager them on games that you’re comfortable with.

With sports betting bonuses, the minimum odds requirement must be followed strictly to complete the turnover requirements of the bonus.

Event Dependency

If the operator hosts tournaments or it’s the holiday season, you can get limited-time offers.

Top bookmakers will offer bonuses for major sports tournaments like the FIFA World Cup or Super Bowl.

Common Types of Bonus

Welcome bonus, deposit bonus, no deposit bonus, cashback bonus, free spins bonus, VIP programs, etc.

Free bets, bet insurance, accumulator bets, boosted odds, cashback offers, rebate offers, etc.
