We are the only one to have an interactive Flash map of Tokyo. We have the most neighbourhoods listed, the most pictures (gallery included) and the most theme guides...
Yes, JREF's maps are one of the best around. Maps are the one area I have really struggled to find a good solution to. People want so many different things from a map; some want a simple one they can print out and take with them, others want great detail so they can drill down to street level detail.
While our main map
http://www.japaneselifestyle.com.au/tokyo/tokyomap.htm is almost useless for printing out, it now has over 140 interactive points of interest. I am still not happy with this as a solution, but we are going to continue to develop it.
JREF definitely has the most neighbourhoods listed which is probably of greater benefit to a long stay visitor to Tokyo. Japanese Lifestyle tends to have more detail about the key tourist destinations. This is more like the typical printed guide book.
JREF also has more pictures, but like Japanese Lifestyle they really need to be better integrated into the travel guide sections so it is seamless for the reader. Clearly the fact that neither of our web sites have done this says how hard it is to do.
My intention of this thread was to find out from end users what they felt were the key advantages and disadvantages of the various sites, but unfortunately it only really seems to be web masters that are commenting.
I still find the Google results for the term "Tokyo" interesting. Clearly Japan-Guide is way out in front at position number one, I am not surprised that wikipedia is at number two, but how did Planet Tokyo get into number three. They don't really have that much content on Tokyo, the only thing I can really see going for them is "Tokyo" in their domain name. As I mentioned earlier, I am surprised that JREF is not in the top twenty given the high traffic volume it receives. (Of course the bulk of the traffic is generated by the top three or four positions, so the difference between position 18 and 60 really makes not difference).
