The world of Pokémon ‍has been a beloved one for decades, captivating​ people of all ages with ⁣its colorful creatures and exciting⁤ adventures. It ⁤has spawned numerous games, TV shows, movies, and‍ merchandise, making it ‌a multi-billion dollar franchise. However,‌ not everything in the Pokémon universe is all fun and games, as recent events have⁢ shown.

On April 20th, 2021,⁣ Japanese authorities arrested​ a ⁢man named Masahiro Sakurai ‌for selling unauthorized Pokémon game modifications. ​Sakurai, who goes ⁣by the online alias “Pokémon Genius,” ​had been offering exclusive creatures and features for players to purchase in the popular game ‍Pokémon Sword and Shield. ​But who ‍is this “Japanese genius” and what were the consequences ‍of his actions? Let’s dive in and find out.

The Rise of “Pokémon⁣ Genius”

Masahiro⁤ Sakurai, 45,⁤ is a resident of Saitama Prefecture in Japan. ​He ⁣first gained notoriety in the gaming community in 2019 when he started offering unauthorized Pokémon modifications for players to purchase. These ‌modifications, also known as “mods,” allowed players to access exclusive content, such as rare ‌Pokémon and in-game items not ⁢available in ⁤the original game. ‌He ‍sold these mods through‍ his website and charged players⁢ up to $60 for a ‍single modification.

Sakurai’s website quickly gained popularity, with players from all over the world purchasing his mods.⁢ But⁣ trouble loomed on the horizon as Nintendo, the company behind Pokémon, caught wind of Sakurai’s activities and filed a lawsuit against⁣ him. The lawsuit alleged that Sakurai was violating copyright laws by using Nintendo’s intellectual property without permission. Additionally, Sakurai was ​also accused of using‍ illegal software to modify ‍the game.

The Consequences of ⁤Selling Unauthorized Pokémon Mods

Sakurai’s ⁤arrest and subsequent legal battle have had significant implications, not‍ only for him but for the world⁣ of gaming ⁣as a whole.

Arrest and Imprisonment

Sakurai was arrested by Japanese‍ authorities on ​April ‌20th, 2021, on charges of copyright infringement and violating Japan’s Unfair Competition Prevention Act. He was ‍taken into custody and ⁤held in jail for three weeks ⁢until his trial.

In⁣ court, Sakurai claimed that he was not aware ​that selling mods was illegal and that he was simply providing‌ a service ‍to fellow gamers. However, the judge ruled against him, stating that Sakurai‍ was ⁤well ⁣aware ​of the potential consequences of his actions. He‍ was sentenced to ⁣two years in prison and a ​fine of 10 million yen (approximately​ $92,000).

Zero Tolerance for ‌Copyright Infringement

Sakurai’s ⁢case ⁣serves as an ⁢important reminder that copyright ​infringement is taken very seriously, and there ​is ⁣zero‌ tolerance for it in industries⁣ like gaming. Companies invest a significant amount of time, effort, and money into creating their products, ‍and unauthorized modifications can ‌have severe consequences for their revenue and intellectual property rights.

Practical Tips for Gamers

The arrest of “Pokémon Genius” ⁢has caused widespread shock and disappointment among the gaming community. It has ⁢also raised some important questions about the use of mods and the consequences of buying them. Here ⁢are some practical tips ‌to keep in mind to⁤ avoid getting‍ involved in similar ‍situations:

  1. Always Stay Informed: ⁢Take the time to research and educate yourself on the​ laws​ and policies surrounding mods​ in your ‍country. What may ​be legal in one country may not be in‌ another.

  2. ​Be Cautious of Unlicensed Mods: ⁤While some ⁣mods are created and sold with permission‌ from the⁢ game’s​ creators,⁣ others are not. Be ⁢wary ⁤of purchasing mods from unknown sources, as they could contain ‌malware or illegal content.

3.‌ Respect Copyright Laws: It’s essential to understand that ⁣using someone else’s ⁣intellectual ‍property without their permission is against the ‍law and can lead to ⁤severe consequences.

Benefits of Not Using Unauthorized⁤ Mods

While it may be tempting ⁣to purchase​ mods to gain an advantage in the ⁣game, there are many ⁣benefits to not using them. These include:

  1. Keeping the Game Balanced: Mods can give players an unfair advantage, disrupting the balance of the game ‍and making it less enjoyable for others.

2.‍ Supporting the Creators: By not using unauthorized mods, ⁤you are supporting the hard⁢ work and creativity ‍of the game’s creators and not stealing from them.

  1. Avoiding Legal‌ Troubles: As ‌seen in the case of Sakurai, getting involved in the ⁣illegal distribution or use of mods can have severe consequences. It’s‍ best to stay away from⁣ them entirely to avoid any legal ​troubles.


As the Pokémon franchise continues to thrive, it’s crucial to‌ remember that⁢ there are ⁢rules and laws⁣ that ​govern the use of its ⁤intellectual property. Masahiro Sakurai’s arrest ⁤serves ‍as a reminder that ‍copyright⁣ infringement is not taken lightly and can‌ have severe consequences. As gamers, we must always be mindful of ‍the legality of our actions and respect the⁤ hard work and creativity of game creators. Let’s keep the world ‌of Pokémon fun and fair for everyone to enjoy.


  • This is a shocking news. I hope justice will be served and the game will be protected from any unauthorized modifications.”

    JohnW: “Wow, this showcases the impact and dedication of Pokémon fans, but also the consequences of going against the rules. Hopefully, this will discourage others from making illegal modifications.
