Google Japan recently added 5 new features:
Just like on the American Google.com with adding 'dictionary' to your keyword to get a description of that word, adding the kanji for 'eiwa' (English-Japanese) or 'waei' (Japanese-English) to a keyword, gives an icon for the translation of that word (example: house [google.co.jp] or 'kasa' [google.co.jp]).
The kanji for company information (kaisha joho) and company name gives a link to a page on Nikkei site with news and information about that company. (Example: Toyota [google.co.jp])
Combine the kanji for stockprice ('kabuka') with the company name, and you will get the link to the related stock information page on the Nikkei site (Muji [google.co.jp]).
Entering <city name A> 'kara' <city name B> (from A to B) will give an train-icon on the SERP with 2 links for train information (Tokyo-Kobe [google.co.jp]).
Parcel delivery information
Just like you can do for some time with UPS and FedEx , it's now also possible for the company 'Yamato' to get parcel delivery information by entering that company name and the parcel code. (1583-2806-9200 [google.co.jp])
Let's hope that the engineers at this new R&D center can come up with other nice features.
