The lack of online maps of Japan with words English has been a nagging problem for visitors here who don't read or write Japanese.
diddlefinger.com goes a long way to addressing that. You can look up Japanese addresses on Google maps even if you only have the English address.
The site is user friendly guiding users through the address search to minimize errors. There is also a zip look-up and you can paste in a Google Maps URL you have been given to see the map on the diddlefinger site. Obviously well thought out.
