If this true, why can't he fly to Jamaica, C'mon let the dude smoke like a broke stove if he wants to he deserves it for his hard work in music.
Unfortunately, whether he wants to or not, deserves it or not, he broke the law. Marijuana is illegal in many countries in Asia - Japan included - and is a serious offense. We can sit and argue about the pros and cons of marijuana, but at the end of the day, he broke the law and that's what matters. As for flying to Jamaica, he will make the situation worse. There might be a court case on his hands right now, and you can not flee the country if you've committed a crime that is considered that serious. Just so you know, criminal offense for possession of marijuana in Japan is a maximum sentence of 5 years in prison and a fine. Yes, he may be able to afford a bail, but his reputation his now ruined.
But, like you said there are consequences
I don't know why you automatically think of Jamaica when marijuanna is involved (you know when the substance is legal in several places on this earth and in several parts of the US)....but ok....
Please read the article or even research a little bit about Japanese laws. He broke the law in Japan, a country that still classifies marijuanna as a controlled substance and if you're caught with it you will face charges. Not to mention the social impact of getting arrested in Japan for stuff like this. Not only will his label drop him, but fans aren't going to forgive him for "sticking out amongst the other nails" like this.
Like you said there are consequences, and he's held responsible.
