"Bas" Hatsanat Piniwat is a Thai-American-Chinese singer and actor born in Bangkok and raised in Chiang Mai, Thailand. His cousin is actor Chaiyapol Julien Poupart. After studying at Montfort College in elementary school, he went on to study at the Thai-Chinese bilingual school Chongfah Xinseng Wanish Bamrung. However, when he quit table tennis and chose to pursue acting, he switched to a GED programme. Afterwards, he enrolled in the Faculty of Communication Arts at The University of the Thai Chamber of Commerce. As a youth table tennis player, he was a District 5 representative (northern region). In national competition, Bas managed to place 2nd runner up. When he was substituted, he decided to make the career change from athlete to singer-actor. Starting out, he landed mainly extra work. It wasn't until "2Moons" (เดือนเกี้ยวเดือน) in 2017 that Bas landed his first leading role. In 2018, he joined the recurring cast of his first Chinese series "Cinderella Chef" (萌妻食神). In February 2018, he made his debut as a vocalist in the boy group SBFIVE (เอสบีไฟฟ์) which disbanded in 2020. In 2023, Bas left Star Hunter Entertainment (สตาร์ ฮันเตอร์ เอ็นเตอร์เทนเม้นท์) and signed as talent under Studio Wabi Sabi (สตูดิโอ วาบิ ซาบิ). Born Suradet Srithongnopphawong, he changed his last name in the beginning of his career before changing his first name to Hatsanat in 2024. In April 2025, he made his debut as lead singer of the duo band This City under Wanlove Music (วัน เลิฟ มิวสิค), a subsidiary of LOVEiS (เลิฟอิส), with the release of their first single "City Lights." Early on in his career, Bas won Young Star of 2017 at that year's Kazz Awards. The next year, he won the 7th Anniversary Attitude Rising Star of the Year 2018 award and the Kazz Awards New Actor award.
