Safety, public transportation, and customer service.
I did for two years. I also go often for business.You live in Japan?
To be honest, you simply can't beat the transport! always on time and so efficient!
I forgot one very important thing I very much appreciate: NO inflation!
In the 8 years that I've come to Japan on different occasions, prices have barely gone up! I can still get beer for the same price in bars as I could in 2008, whereas it has almost doubled where I come from. The same goes for public transport, food, etc.
This might change of course with tax increases, but so far it is the only country I've been to with this low level of rising prices.
The cold weather is killing me...
Walking 10 km per day between visits, with a bunch of time waiting on train platforms with no heat has convinced me that Tokyo is not where I want to be. Next year I'll either have a vehicle with some heat, move south, or be out of the country. I'm too damned old for this.
Winters in Kanto are actually quite mild. It's fabulous to be able to use the bicycle almost all year round. Short bibs in December, that's a first though.
I love my home country, America, but I will not return unless forced (political tensions with S. Korea and Japan are on my radar for this as the U.S. might cause disdain in the region).
Nonetheless, I'll ride it out as long as possible in Okinawa.
Stationed here in 07, returned to the US for about 6 months in 09 trying to find any sort of work, realizing that it wasn't the best place to raise a family, and left by mid-09 losing all of our transported household goods to begin all over.How long have you lived in Okinawa?
