If you are in Japan and thinking for an investment you should consider buying stocks.
In Japan there is many online trading companies which you can sign up to buy stocks. My recommendation is Monex, which has pretty good deals and lots of resources to get information about stocks and other investment possibilities.
Using Monex you have pretty good freedom to buy stocks using tools such Mini Investment(english). This means you can buy even stock with 10000 Yen starting with this possibility.
If you are searching nowadays for a good investment, I would recommend Nintendo (TYO:7974). The stock showed a good performance in the last year term and also as a company it had solid numbers on profits.
Also whoever knows about Wii will know that is good console which will be compare to other console such as Xbox 360 or Playstation 3 better sales, because of its unique interface which speaks for more broader public.
As of Thursday, January 25th 2007 the Closing Price of the Stock in the Tokyo Stock Market was 33350￥. According to many analyst it has good solid possibilty of 40000 ￥ or more.
What do you think about Nintendo and it's stock? Should we be part of it?
