Tsuru Captial

What We Do

Tsuru Capital is a proprietary trading fund. We believe in using well written software to design and execute efficient trading strategies in financial markets. Our strategies are all objective and are as far as possible executed by the software itself. There are no ‘traders’ as such—everyone contributes to the improvement of the core strategy along with any related analysis tools and software infrastructure. Our main focus is on markets where we can execute low risk strategies with good returns—these tend to be high volume with low margins—which allow us to make money without taking large positions.

Currently we do market-making on index futures and options, on active listed markets. Our edge is in superior strategies and efficient low latency execution. We use the Haskell programming language almost exclusively since we believe it gives the best combination of high-level flexibility, elegance, safety and performance.


We have a SOHO-style office located in Tokyo, with casual atmospheres. Please see our employment page for details.
