Even if the tours were will still in operation it’s unlikely your friend would have been able to benefit from them as she wouldn’t be able to get to Narita Airport before 3pm. Incheon Airport in South Korea .has a similar scheme that is still running, it’s only for people who are around in the morning and very early afternoon.

Narita Town is extremely easy to navigate. When I built an itinerary for my parents I included a short stay here for their final night so that they could amble around the town and temple before they boarded their flight back to Europe. It holds its own against many other neighbourhoods and destinations in Japan.
