The Japanese pair Takahashi/Tran decided to split. They got bronze at last year's world championships giving Japan the first world medal in this category. As they are very young, they hadn't developed their full potential yet and it looked like a very promising couple for the future. Problems started to happen during the summer when Narumi caused an injury that would have left them far from the competitions.
But the main reason for the split might be the impossibility to get Japanese citizenship for Mervin Tran before the 2014 Olympics. They will both continue their competitive career with other partners.
