Nah, I don't think he's in any trouble, well besides this. Considering this is allegedly and it wasn't found on his person, he should be fine unless they search his house and find more. I personally know some rappers who spent like 3 years for weed, so it can be serious shit.
^Yeah, it feels extra surreal because recreational pot just became legal here recently, so I'm seeing ads for cannabis products everywhere and hearing all these news reports about what a booming industry it is, but then this kind of reaction is still happening in Japan. The zero-tolerance attitude the Japanese media and record labels take towards things like this still just feels so over the top.
Both of my favourite (ex-)members of KAT-TUN got arrested for the same thing recently, and they both had all their music activities cancelled, gave tearful apologies to the press and disappeared for a bit, so I feel like that's probably going to be the pattern this follows as well...
