「１０９」は「東急」を数字にあてて名前にしたもので、通称は「まるQ」、この１０９は年間を通して売り上げの低い店舗は退場するルールがあり、売り上げ競争が激しく、この為に建物全体に活気があふれている。

また、店舗の店員は流行のファッションを着て販売し、お客も店員に自分のファッションについてアドバイスを貰うことが多い。

This building was originally a store that sold all kinds of clothing, but while other sales were sluggish, only fashion for young women was growing significantly, so the entire building was dedicated to fashion for young women.

``109'' is named after ``Tokyu'', and is commonly known as ``Maru-Q.'' This 109 has a rule that stores with low sales throughout the year are forced to leave the store, and sales competition is fierce. The whole place is full of energy.

In addition, store clerks wear and sell trendy fashion, and customers often ask store clerks for advice on their own fashion.
