Since China's Stockmarket is shall we say - poor, a lot of money both from Global and Chinese is going into Japan. Partly because it's freeing up cross-shareholdings but also because it's an easy switch/no-brainer. Now if Nettetsu can't find a partner for RXM under those conditions I'd be surprised. Noting, in Japan the mates of Share s that form informal conglomerates so common they are called Kieretsu* in Korea, Chaebol.
