How do I address this japanese address correctly?

Question:

154-0024　東京都世田谷区三軒茶屋2-11-23サンタワーズB棟6階 Tri-Stone Entertainment Inc. (name here)

In Romaji please and thank you!

Answer:

(somebody's name and title,) c/o
Tri-Stone Entertainment, Inc.
Tokyo-to, Setagaya-ku, Sangenjaya 2-11-23
Sun Towers, B-building, 6th floor
Japan
154-0024

(Also if you wanted to, you could cut and paste the Japanese address in Microsoft word, print it out, and tape it to the package/letter as well just to be sure----but
you will be surprised how good Japanese post is. My parents mess my address up all the time, and it remarkably still makes it to my house.

Remember Japanese are opposite of the USA

Japan
starts with large geographical area and works its way down. we do the opposite.
state/city (Tokyo-to)
district (Setagaya-ku)
street address (Sangejaya ......)
building, room: B tower, .....

(Don't forget to write Japan boldly--so it doesn't get sent to Jamaica.)
And for heavens sake don't forget the postal code. (7 digit number)
