"Building upon our nearly 40-year track record in global equities, and our five-year track record of demonstrable success as an active and engaged investor in Japan, we believe the time is right to open our offering up to a new class of UCITS investors," he said.
"After decades of ever lower interest rates we are firmly in a different regime, with higher rates and quantitative tightening presenting a challenge for equities generally."
He added: "We believe the baton is being passed firmly back to stock pickers. It is an opportunity rich environment and one where engagement and a focus on investments with explicit catalysts will be key levers to drive absolute and relative returns."
