Good used cars are readily available in Japan for $1,000 (or less).
Yeah, I've noticed that too but the shaken (road tax + car roadworthiness check) can get expensive too - about $1000 or more every 2 years. One of the plans for our "perpetual traveller" portion of retirement is to buy an older car in Japan and spend 6 months to 1 year travelling through the 4 main islands (Honshu, Shikoku, Kyushu, and Hokaido) and hit a lot of the small towns. We would probably try to sell the car at the end of the trip if possible and if not perhaps just "donate" it to a relative.
We've put most of our current savings into perhaps the most conservative investment there is outside of a passbook account, i.e., U.S. Savings Bonds (a combination of EE and I bonds). When we retire, we intend to convert most of our assets into TIPS.
You may want to think about at least having a small portion (20% at least) in equities. I'm not sure how old you are but if you've got a long retirement planned then you will need some growth.
By the way, despite popular belief, it isn't that much cheaper to live in a 3rd World country -- basically, "services" are very cheap, but "goods" (especially those that are imported) are at least as expensive as they are in the States.
That's true for the imported goods but a lot of the cost savings is that those imported goods and even the locally produced durable goods only make up a small percentage of one's expenses. If you can reduce the cost of half the things (or likely more) in your budget that are "consumables" (food, rent, utilities, etc.) then that obviously reduces one's overall expenses. Also, many of the locally produced "durable" goods one can buy in 3rd wold countries can be quite a bit cheaper. Just my experience from trips to Thailand, China, India, etc.
