Dear Fanny, Thank you for your inquiry. It is possible to purchase kids ICOCA at any JR-WEST ticket office including Sannomiya(三ノ宫)and Namba. Inorder to buy kids ICOCA, passports must be presented to confirm the names ofyour children, and birth dates at theticket office. We look forward to serving you. Sincerely, JR-WEST昨天终于找到客服信箱了,附上JR west的回复。昨天发文问是因为官网所指出的儿童icoca贩售地只有关西空港和京都车站。以上供大家参考
