- Contractual Purity: Being Johnny idols, they are not allowed to reveal their dating lives to the public, in order to keep up the illusion of an 'attainable' guy. They are also not allowed to publicly announce their relationships until they turn 30, and can only marry after 35.
- Ear Worm: Most of their songs are this. As in they will never leave you.
- Ho Yay: Oh so much. Nino enjoys molesting Ohno at any opportunity he gets to the point where Ohno has given up trying to stop him, although he did once refer to Nino as 'the touching man'.
- Ohno and Nino have also repeatedly told everyone they're going out and Ohno ran around stage saying that he wanted to be penetrated by Nino.
- Frankly all of Arashi have been guilty of molesting Ohno and have even managed to work it in to their dance choreography.
- Aiba enjoys showering with the other members, once walking in naked into Nino's shower exclaiming 'Special Delivery.'
- Aiba has also asked Nino to stop wearing flashy underwear as it makes him 'excited'.
- Arashi also have an obsession with each other's nipples forcing each other to wear shirts with holes cut out for them to see.
- By this point every member has kissed every other member.
- Just watch the music video for Kitto Daijoubu.
- And the video for Happiness.
- Portmanteau Couple Name: Ohno and Nino came up with their own one, Ohmiya SK.
- Viewer Gender Confusion: They're already girly looking enough, and when they put on womens clothing, even seasoned fans can make a slip up and think they're girls.
YMMV / Arashi
