This is a thread about day trading/short term trading so I am not sure how relevant your fundamental long term views are with Nintendo and their hardware intentions over the last 10 years. I know it was just an example of one of the problems you have with that market as a whole but if you are a day trader trying to flip shares you really don't care about those sorts of things.I can give you a very short answer to why I am so negative on the Japanese market:
Japanese politicians and business leaders are incredibly arrogant and still have not hit the wall. They feel they innovate (very few nich markets are such as fanuc), they feel they innovate but they don't understand consumer needs anymore and instead create stuff and brainwash Japanese consumer of a need for stupid products. Look at Nintendo. It took them 2 decades to open up their game library to other platforms. Their hardware inventions over the past 10 years is ridiculous. Look at Sony. Look at Panasonic or Toshiba or Sharp. All completely misread the international and Japanese market and demand.
The stock market in particular is riddled with short sell restrictions en Masse, small stocks are manipulated by the mafia, especially small property developers and pachinko stocks. Look at Glee, a company that is built entirely on gaming addiction and making users shell out hundreds if not thousands of dollars for in app purchases. Then commission cost to trade are sky high. Illiquid stocks en Masse. And transaction taxes. Need to list more?
However, your points about high commissions, lack of liquidity, transaction taxes and the many short sell restrictions are valuable info. Thanks for sharing that. I think your response has persuaded me along with many of the other folks that will read this thread.
