The Japanese star joined the Gunners in August 2021 from Serie A side Bologna and has made 73 appearances in all competitions.
Tomiyasu's new contract is reportedly for two years, with the option of a further 12 months.
Manager Mikel Arteta said: "We are so pleased to have Tomi commit his future with us. Together with his natural ability and strength, Tomi's attitude, mentality and values are first class.
"Tomi is loved by everyone and has been an integral part of the squad since joining us. The way he trains, with his desire and determination to be the best version of himself every day, is admirable. We look forward to continue working with Tomi in the future years."
Tomiyasu has made 20 appearances this season, scoring his first goal against Sheffield United in October, but has not featured in 2024 having played for Japan in the Asian Cup and then struggled with a calf injury.
The 25-year-old said: "I'm so happy to extend my contract because Arsenal is one of the best clubs in the world. And it's a dream to play for this club.
"I'm still learning a lot of things from Mikel, from my team-mates. I still have capacity to improve. So I will try to be a better player and also a better person as well."
