History
History
CTW Inc. (originally CTW株式会社) was founded in August 2013, with Ryuichi Sasaki as president. CTW transitioned to developing HTML5-based browser games in the mid-2010s. In October 2018, CTW launched its gaming platform, G123, which provides instant-play games primarily adapted from popular anime and manga franchises. By 2024, its users had increased to more than 500 million. In 2021, CTW began expanding its international operations and released localized versions of its games in English and other languages. In 2023, CTW reorganized under a Cayman Islands entity as CTW Cayman. Two years later, in 2025, CTW filed to list on the Nasdaq as CTW Cayman. On August 6, 2025, CTW Cayman was listed on the Nasdaq.

Criticism
Internationally, CTW and its G123 platform has faced criticism regarding its advertisements which were frequently seen throughout a number of social media platforms worldwide. Similar to mobile game ads, G123's ads use exaggerated and / or misleading content that are not present in the actual games that G123 tries to advertise. In 2025, the Advertising Standards Authority opened an investigation into CTW after three controversial adverts that were advertising High School D×D: Operation Paradise Infinity, a browser game based on the anime series High School DxD, contained unsuitable, potentially harmful content which violated a series of CAP codes, primarily 1.3, 4.1, 4.8 and 4.9. After being contacted by the ASA, CTW immediately removed the ads while also reinforcing review and approval processes to comply with ASA's CAP code.
