should the japanese sayings from certain costumes in SMM be translated?

[Lord Bowser]

there are a few costumes in SMM that have their characters say something in japanese. the ones I know of are;

• shulk
• mary o.
• arino KACHO
• barbara the bat
• yu ayasaki

though I'm pretty sure there are more.
should we translate them or leave them be?

 

[Ray Trace]

uh, why shouldn't we translate them? this is an english wiki after all.
