Kanye West traveled to Tokyo last week after days of frenetic tweeting in which he clashed with ex-wife Kim Kardashian about the co-parenting of their daughter, North. Kanye “instantly calmed down after all of those controversial, offensive rants he spewed on social media,” insiders said. West can be in an erratic state of mind when in Los Angeles, insiders revealed, but feels peace when in Tokyo which sources described as “completely disconnected and calm.”
