Mirai was taking the children's lessons offered by Meiji Jingu Skating Rink, a year-round skating facility and training center, which offers three consecutive mornings of classes during holiday breaks, and weekly group and private classes through the year.

Straight rows of pink and orange traffic cones had been used to divide the rink into practice areas for classes, grouped by age and skill.
