Mrs Kobayashi said Yuzu was back on the ice later than it was planned. He has started skating, but she doesn't know about jumps and spins.
There was no official announcement that he was back on ice in May. That talk came about because someone mentioned that she read in a magazine that he was back on the ice in May, but they could not recall which magazine. Thus; it could not be verified for accuracy. Refer to
