Yeah Japanese people probably experience quakes on a daily or weekly basis but I think you might be underestimating the problem a bit. The government study was talking about a MAJOR quake, closer in scale to the 1923 Tokyo quake which wiped out a third of the city, and hundreds of thousands of buildings, than to the regular mini quakes.

A professor at Cambridge put it something like, historically, a major quake hits Tokyo every 50 years - the last one to hit it was in 1923, so it's been building and building and is now overdue.

Oh yeah, forget about the 50 years timeframe I quoted earlier, the study has another finding: 70% chance of a major quake sometime in the next 30 years.

A major quake could very possibly wipe out the entire value of BJT shares, remember they have borrowed heavily to purchase the buildings and are 100% uninsured against quakes.

Well that's just my opinion, I personally prefer to play it safe, but I can see if you don't mind living with a bit of risk and then BJT should be fine for you. Best of luck BJT holders.
