Hello. I will be flying to Tokyo this Monday and was wondering if it is still snowing and if I need to bring winter boots. I would like to pack very lightly and was planning on wearing leather sneakers. However, I am afraid that they might not keep my feet warm enough if it is still snowing. Could somebody please advise me if there is a need to bring winter boots? I will be attending a trade show at Makuhari Messe and then will visit Disney Sea. Thanks in advance.
