On New Year’s Eve, ProWellTech Japan chief editor Hirohide Yoshida passed away at the age of 49. In addition to being an extremely valuable member of our international team who helped build the site’s presence on the international stage, Hiro-san was a caring, warm and kind colleague who influenced the lives of those of us who have had the pleasure to work with him.
I’ve worked alongside Hiro-san in two consecutive ProWellTech Tokyo events. The size and scale of the shows were an impressive testament to the team he led, as was his passion for technology. In all of this, he was an ideal ambassador for a community of electric startups and tech journalism, a passion evident in every aspect of his work and life. He continued this vision as he helped turn the conference into a virtual event during the COVID-19 pandemic.
He leaves him with his wife, two young children and a site and staff that will continue to carry his brand for a long time to come.
ProWellTech Japan has published their thoughts on Hirohide Yoshida’s life and career which you can read here. We asked the site editor, Takya Kimura, to share additional thoughts below,
He started his career in KADOKAWA / ASCII. For over 20 years he has been writing articles on Apple and tech companies. With his in-depth knowledge, he became editor-in-chief of MacPeople, a magazine for Apple fans e ASCII weekly, publications he directed for eight years.
In 2018, he became Editor-in-Chief of ProWellTech Japan. He was an incredibly hard worker, with a long-term view, who never made a complaint about work. As TCJ’s Editor-in-Chief, his team has run ProWellTech Tokyo, Japan’s largest startup event for three consecutive years, including its first online event “ProWellTech Startup Battle Online 2020”.
Until the last moment, he loved his wife, his newborn twins, his cat and ProWellTech Japan. After his long journey, he now rests in peace, wearing his beloved ProWellTech Japan t-shirt.
