Inside Mark Zuckerberg's unconventional billionaire life - from raising beer-drinking Highland cows on his ultra-secretive $100M Hawaiian compound to crafting his own Japanese sword

Mark Zuckerberg lives a life that is far from ordinary - not just because of his extreme wealth, but also because of his eclectic taste in activities.

This week, the 39-year-old Facebook CEO posted videos of himself on Instagram creating a Kitana sword with the help of Japanese sword master Akihira Kokaji. 

Zuckerberg had been in Japan to meet with the Japanese Prime Minister Fumio Kishida about artificial intelligence and to celebrate his wife, Pricilla Chan’s, 39th birthday.

In addition to sword making, Zuckerberg also spends his time caring for a herd of cows that drink beer and eat macadamia nuts on his $100m luxury estate.

The billionaire who is living the highlife worldwide has a $173 billion net worth.

Zuckerberg became a billionaire when he was 23-years-old after Facebook went public in 2012.

He currently owns 10 different properties, including his top-secret Hawaiian compound that features multiple mansions and a 5,000 square foot underground bunker.

His island home in Hawaii is also where he raises a herd of cattle and is aiming ‘to create some of the highest quality beef in the world.’

He began raising the cows at Ko’olau Ranch on Kauai - an island in the Central Pacific.

According to Fast Company, Zuckerberg could spend between $180,000 and $360,000 a year on food for each cow.

It’s unclear if Zuckerberg’s homemade Japanese weapon also resides in his Hawaii home, but according to Samurai Swords.Store, an authentic katana sword can cost around $12,000 to more than $25,000.

Another one of Zuck's expensive toys is his Gulfstream G650 private jet, which he used to travel to Asia.

Zuckerberg’s company Meta Platforms, Inc. spent a whopping $1.6 million on air travel back in 2021 and another $6.6 million in 2022.

The businessman that lives the billionaire life also has time to pursue other interests outside of work, including jiu-jitsu.

Zuckerberg’s passion for MMA has led him to work with UFC stars Israel Adesanya and Alexander Volkanovski.

However, the tech billionaire’s interest in the sport has not come without a price.

He’s suffered multiple injuries during his training sessions, including a tear in his anterior cruciate ligament (ACL) last year while training for a competitive fight.

Zuckerberg underwent knee surgery in November 2023 and came out of the procedure feeling ‘grateful for the doctors and team’ that were taking care of him.

The injury is not stopping the entrepreneur from his MMA fighting and wrote in the caption that he is ‘still looking forward to doing it’ after he recovers.

According to Care Credit, the national average price for ACL surgery in the US is $15,445, but the cost of the procedure can range from $9,504 to $26,137.

The billionaire likely had no problem covering that surgical bill, but if he continues to pursue his MMA fighting activities, injuries like concussions and muscle tears could land him in the hospital again.
