The firm is targeting healthcare, consumer and equipment manufacturing companies that have plans to expand their operations in the Asian region.
Shunji Katayama, the new managing director of Olympus Capital, told Bloomberg: "Japanese companies are looking to operations in Asia as their home market matures.
"We can provide risk money and know-how, supporting them as they operate in China and other countries."
The move follows a recent World Bank report forecasting that the growth rates of developing nations in east Asia will outstrip that of Japan in the next two years.
It stated that Japan is likely to grow at 2.5 per cent this year and 2.1 per cent in 2011, while its counterparts will record equivalent growth of 8.7 per cent and 7.8 per cent.
Last month, Japanese prime minister Naoto Kan warned that the country's economy could collapse unless action is taken to cut the size of the public debt.
