Kakaku has announced the launch of a new version of Tabelog, its popular restaurant search and rating service, for the iPhone. Version 4 enables iPhone users to contribute information, reviews and pictures to a given restaurant in Japan directly through their handsets (download).
Kakaku has also redesigned the look of the Tabelog app, which now detects your location automatically right after starting it and lets you search for good restaurants in the vicinity right away. Some features are just accessible for Tabelog premium users, however ($3.80 monthly fees).
I compiled more information about Tabelog and its position against Gourmet Navigator (Gurunabi) here.
