Japan Arrests First Alleged Nintendo Switch Modder, Marking New Era in Video Game Piracy

by David May 18,2025

In a groundbreaking move against video game piracy, Japanese authorities have arrested a 58-year-old man for the first time for modifying Nintendo Switch hardware. The arrest, which occurred on January 15, was reported by NTV News and translated by Automaton. The individual is suspected of breaching the Trademark Act by altering Switch consoles to play pirated games and then selling them.

The suspect allegedly modified second-hand Switch consoles by welding modified parts onto their circuit boards, enabling them to run pirated games. He is accused of loading these consoles with 27 illegally obtained games and selling each unit for ¥28,000 (approximately $180). The man has confessed to the charges and is under further investigation for potential additional violations, according to the police.

Nintendo, a company that has long been combating piracy, recently took action in May 2024 by issuing a takedown request targeting 8,500 copies of the Switch emulator Yuzu. This followed the emulator's shutdown two months earlier. The initial lawsuit against Yuzu's creator, Tropic Haze, highlighted that Nintendo's flagship game, The Legend of Zelda: Tears of the Kingdom, was pirated over one million times before its official release in 2023.

Legal efforts to combat piracy are intensifying. Nintendo successfully sued the game file sharing website RomUniverse, securing $2.1 million in damages in 2021 and over $12 million in 2018. Additionally, Nintendo's actions led to the blocking of the GameCube and Wii emulator Dolphin from being released on the PC game platform Steam.

This week, a patent lawyer representing Nintendo shed light on the company's stance on piracy and emulation. Koji Nishiura, Assistant Manager of Nintendo's Intellectual Property Division, stated, "To begin with, are emulators illegal or not? This is a point often debated. While you can’t immediately claim that an emulator is illegal in itself, it can become illegal depending on how it’s used."
