A good friend and I are going to Tokyo for a few days in August, and last night we were looking up how to travel from the airport to the city. We'll be taking the Narita Express, a brand new, state-of-the-art high-speed train. This train may be the best of the best, but they should probably have someone check out their website. We read the following:

Babies (up to 12 months) and infants (1 to 5) generally travel free, though a child's ticket is needed in the following cases:

• When three or more infants accompany one adult or a child, child's tickets are needed for the third and subsequent infants.
• When an infant or a baby occupies its own reserved seat or berth.
• When an infant travels alone.

When an infant travels alone? Can you just picture that? Hahaha.
