Subject: Re: BRK's Japanese holdings
First of all, I hate IB. That said, they are pretty much the only game in town to buy a large variety of "native" foreign shares that I'm aware off (Fidelity will do it, but charges an arm and a leg. Vanguard will buy "F" and "Y" shares of those stocks that offer them, but levy an additional cost and, frankly, many of those shares are thinly traded, so pricing can be an issue).
I own shares in stocks of a number of countries. Other longer-term Japanese holdings include Softbank (been "lucky" with tech for aa long time), Seven & I (7-Eleven), Fanuc and Omron and more recently Fast Retail (known for their Uniqlo line).
