I the name and came up with a fitness gym and a department store both called Lafore. Is that what you are looking for?
Here's how I would write it
Lafore Shinjuku Ten (store/branch)
Lafore Shinjuku Bldg 0.5 floor
1-11-6 Jingu-mae, Shibuya-ku (ward)
Tokyo, Japan (I don't think you need to specify "to" if you write the name in English)
〒150-0001
JAPAN
and if you're writing a letter to this address, don't forget to write AIR MAIL in big letters somewhere
