MODIのオペレーションを行う丸井は元々三越、西武などの大人向けの百貨店に対し、若者向きの品揃えをして男女を問わず１０代から２０代の若者を惹きつけてきた。

しかしながら、ユニクロ・無印などの新しい形態の店舗、ハンズ・ロフトのような他にない商品の品揃えの店が台頭してきたことにより、その居場所を新たに探す局面になってきた。

「モディ」は丸井が「マルイシティ」を「モノ」から「コト」へ、更に「トキ消費」（その時、その場所でしか体験できないイベントやフェス）から「押し活」（有名人やアニメのキャラクターにお金を使う）に変化する若者の好みに合わせてつくった店舗になる。

入口の階段を下ると、大きくPOP　STARの写真が並べられて、その上には上映中の映画の広告、左手にはPOP UP STOREが作られている。

Shopping, dining, etc. for foreign visitors,
MODI

Marui, which operates MODI, originally attracted young people in their teens and twenties, regardless of gender, by offering a selection of products aimed at young people, as opposed to on department stores for adults such Mitsukoshi and Seibu.

However, with the emergence of new type of stores such as Uniqlo and Muji, and stores with unique product selections such as Hands and Loft, it has come to a point where it needs to find a new place to be.

Modi is a store that Marui has created to suit the tastes of young people who are changing Marui City from "things" to "experiences" and from "time consumption" (events and festivals that can only be experienced at that time and place ) to "oshikatsu" (spending money on celebrities and anime characters).

Going down the stairs at the entrance, you will see large photos of pop stars lined up, above them are advertisements for movies currently being shown, and on the left is a pop-up store.
