    Ikuhiro Ihara

    Software Egineer at Twitter

    Ikuhiro Ihara was a highly respected senior software engineer at Twitter who made significant contributions to the platform's development. He is best known for his role in leading the push to expand tweets from 140 to 280 characters, a major change that impacted how users interact with the platform.123

    Career at Twitter

    Ihara worked as a senior software engineer at Twitter, where he was involved in several important projects:

    1. Character Limit Expansion: He played a crucial role in expanding the tweet character limit from 140 to 280 characters.5 This change was implemented to address the disparity in information density between languages, as Ihara noted that when tweeting in Japanese, he could express much more within the original character limit compared to languages like English.5

    2. Ad Recommendation System: Ihara had four years of experience working on Twitter's ad recommendation system.1

    Departure from Twitter

    In a surprising turn of events, Ihara was among the employees fired by Elon Musk during a round of layoffs that occurred on November 23, 2022, the night before Thanksgiving.124 This decision came as a shock to many, including Ihara himself, who was reportedly supportive of Musk's vision for "Twitter 2.0".4

    Previous Experience

    Before his time at Twitter, Ihara's professional background included:

    • Software Engineer at Amazon Japan
    • Software Engineer and Manager at livedoor

    Ihara's contributions to Twitter, particularly his work on expanding the character limit, have had a lasting impact on the platform's user experience. His unexpected departure from the company during Musk's restructuring efforts highlighted the significant changes occurring within Twitter's engineering team.
