The most common way to contract words in Japanese is to take the first two characters (AKA kana) of each of the first two words (excluding particles) and combine them.

A number of SCANDAL songs with titles in Japanese are rather long and can be tedious to type them out, so just as an FYI, here's how to properly shorten the titles of a few of their songs (which are also used by Japanese fans and as well as SCANDAL themselves):


Awanai Tsumori no, Genki de ne = AwaTsumo
(会わないつもりの、元気でね = 会わつも)

Onegai Navigation = OneNavi
(お願いナビゲーション = おねナビ)

(キミと夜と涙 = キミ夜)

Koi no Gestalt Houkai = KoiGes
(恋のゲシュタルト崩壊 = 恋ゲシュ)

Koisuru Universe = KoiUni
(恋するユニバース = 恋ユニ)

Konya wa Pizza Party = KonyaPizza/KonPizza
