本論文是針對岩井俊二導演的電影作品《情書 Love Letter》，將重點聚焦於 記憶」上進行論述。在岩井導演所製作的電影中，經常被指出「記憶」是重要的要素。特別是在以描述已逝去之過去人物為中心的《情書 Love Letter》中，記憶可說是重要的主題。 因此，本論文將根據登場人物的「記憶」，從「消失的記憶」「不會消失的記憶」「復甦的記憶」等觀點進行論述，最後則是針對電影劇名之情書，對記憶進行探討。 首先，在第 2 章中指出，透過人們消失的記憶，反而會讓尚留有記憶的人的人物形象變為更加鮮明之可能性。此外，在第 3 章中，仔細觀察那些不會消失的記憶，可得知此故事都是環繞在早夭的藤井周遭的事物。第 4 章則是闡述，樹透過深究自己復甦的過去記憶，得知藤井其實很有可能對女朋友抱持好感。最後，在第 5 章指出，此電影中的 3 封情書，無論是哪一封情書都是單向面的。

This paper discusses the film Love Letter, directed by Iwai Shunji, focusing on “memory”. It has often been pointed out that “memory” is an important element in the films produced by director Iwai. In particular, memory is an important theme in Love Letter, which focuses on a person who has passed away. Therefore, in this paper, I discuss the “memories” of the characters in terms of “forgetting,” “retaining memories,” and “reviving memories,” and finally, I discuss the love letter—which is also the title of the film—in terms of memory. First, in Chapter 2, I point out that through people’s lost memories, there is a possibility that the personalities of those who have kept their memories are revealed. Next, in Chapter 3, I look closely at those memories that have not disappeared and find that they are concentrated on those related to Fujii, who died young. In Chapter 4, by examining the past memories revived by Itsuki, it is revealed that Fujii actually had a strong liking for her. Finally, in Chapter 5, I point out that there are three love letters in this film, all of which are directed one way.
