Rock band PLASTIC TREE just released their new single, "Mirai Iro", on December 15th, and the track even made it into Oricon's top 10. They were also supposed to do two lives, one on December 28 and one on the 29th at JCB HALL in Tokyo.

But all that has changed now that vocal�Ryutaro has been diagnosed with Guillain-Barre syndrome. Earlier today (25th in Japan), Ryutaro, who had been complaining about how sluggish he's been feeling, went to see a doctor. Although he thinks he's still able to perform, the band has come to the decision to cancel both performances.

Even though the concerts are cancelled, they will still sell the concert goods to those who purchased tickets.

For those of you who are not familiar with Guillain-Barre syndrome, it is "an acute inflammatory demyelinating polyneuropathy (AIDP), a disorder affecting the peripheral nervous system." It's usually caused by an acute infectious process and the diagnosis is usually found in "rapid development of muscle paralysis, areflexia, abesence of fever, and a likely inciting event."
