Miki, Akiko, and Oda had a retirement ceremony on Thursday in Nagoya Figure Skating Festival.
I don't read Japanese, so I hope someone who is proficient in Japanese has more details on it!
Meanwhile, some photos can be found in the following links:
Thank you skaters, we loved watching you grow and see your career blossom (of course with ups and downs).
I prefer Yuna and Caro's skating style but Miki was surely one of the sweetest and kindest skaters to the fans when I traveled to competitions.
