In Japan taxis are very pleasant, but expensive, and can be complicated.

I say pleasant because the drivers are usually super-polite, dressed in a neat uniform, quick to get out of the car to help you, keep their cars immaculate, etc.

I say complicated because Japan has an infernal resistance to using street names and marking addresses. If you can get your destination to appear on the "navi", you're OK. If not, you'll be doing a lot of "more towards the castle" and similar guesswork.

Could you tell the driver a GPS address?

If you know it, probably. But if you don't, and if the navigation system doesn't know, it's going to be hard. The street numbering is different from the West.

In Japan and South Korea, a city is divided into small numbered zones. The houses within each zone are then labelled in the order in which they were constructed, or clockwise around the block.

Korea introduced street names and house numbers a few years ago and the new system is now the only official, though of course the former system is still popular. For taxis usually you still name nearby landmarks but they can also input a (western-style) address into their GPS.

Usually, they can tap in the phone number of your destination and it will come up. That's a popular way to use in-car GPS here, and reasonably reliable.

Japan's amazing urban geography doesn't seem like something Uber can fix, surely.
