Mark Zuckerberg's latest passion project? Crafting swords with a Japanese sword master

• Meta CEO Mark Zuckerberg has shared a post of himself helping to make a sword.
• The tech boss enjoyed a masterclass with Japanese sword maker  Akihira Kokaji.
• Zuckerberg is on a mini-tour in Asia and is also scheduled to meet Facebook developers in Tokyo.

Mark Zuckerberg has picked up a new hobby.

The Meta CEO posted pictures and videos of himself learning to make a Katana, a Japanese sword with a curved, single-edged blade, under the guidance of sword master Akihira Kokaji.

The videos show Zuckerberg helping to construct the weapon and then wielding the finished product.

"Really special afternoon learning about making katanas with master akihira.kokaji -- thank you for sharing your craft with us!" he said in an Instagram post.

The tech CEO is touring parts of Asia with his family. He is due to meet Facebook developers in Tokyo on Monday and Tuesday, Bloomberg reported.

Zuckerberg is reportedly set to discuss Meta's large language model, Llama, and Meta's Quest headsets as the company faces increasing pressure from Apple in the VR headset space.

The trip also involves stops in South Korea and India to meet business and government leaders, the report said.

Representatives for Zuckerberg did not immediately respond to a request for comment from Business Insider, made outside normal working hours.

Zuckerberg has shared several other personal posts over the years, some more awkward than others. The Meta CEO recently announced he was raising cattle that would drink beer produced on his sprawling estate.

The tech boss also recently used his platform to share a video comparing Apple's Vision Pro with the Meta Quest 3. Zuckerberg, unsurprisingly, concluded that Meta's device was better.
