Amazing Firms: Shunji Iwai

Love Letter

"Love Letter"(1995 firm) is: Though her fiancé Itsuki Fujii died in a mountain climbing accident over two years ago, Hiroko Watanabe is unable to move on. After a ceremony marking Itsuki's death, Hiroko pays an emotional visit to his mother. There she discovers his boyhood address in an old high school yearbook, and, on a whim, she writes a letter addressed to her old lover. Needless to say, she is more than a little surprised when she actually gets a response from Itsuki Fujii. This Itsuki Fujii, however, is a young woman working at a library and suffering through a particularly tenacious cold in the snowy expanses of Hokkaido. She also endured three years of classroom taunts at having the same name as her male classmate as junior high student-the same male Itsuki Fujii that Hiroko eventually fell for. Though the female Fujii initially worries that she has somehow been targeted by a lunatic, she and Hiroko begins to develop an odd sort of correspondence. The two begin to piece together their respective memories about the male Itsuki, revealing a love lost and a love rediscovered. (from allmovie.com)

The sentence of "revealing a love lost and a love rediscovered" is exactly correct for its firm. 

From Amazon.com, you can get his another firms such as "All About Lily Chou-Chou" (2001) or "Hana and Alice" (2004). Both of them are performed by so cute and talented actress "Yu Aoi"(I really LOVE her). But if you like such Iwai's firms, you should find and see the other one - "Swallowtail Butterfly" (1996). 

Swallowtail Butterfly

"Swallowtail Butterfly" takes place in an alternate Japan, in a ghetto where immigrants from all over the world have come to live and make their fortune. The city is called Yentown, and it is much like Tokyo. Sixteen-year-old Ageha, a young girl whose mother has just died, is passed on from person to person until a prostitute named Glico finally takes pity on her. Under Glico's care, Ageha has many experiences with the other poverty-stricken immigrants in Yentown. Eventually, due to a sudden twist in fate, the immigrants are given a chance to realize their dreams. But in doing so, they destroy their solidarity, and have to face their problems separately.(from Wikipedia)

Glico is acted by "Chara" who is not an actless, is a famous singer in Japan. You can see pieces of the movies what I mentioned by Youtube. You will see that and recognize that their music are so nice and beautiful (I really LOVE them). You can get their OST by Amazon.co.jp, not Amazon.com. Or to search them by 4shared.com etc.
