This episode marks the last time Stephanie says, "How rude!"
The episode is referenced again 25 years later in the Fuller House (2016) episode My Best Friend's Japanese Wedding (2017) when they see Jesse on a Japanese billboard with "Forever" emblazoned on it.
The title is based on one of the many "Road" films made by Bing Crosby, Dorothy Lamour and Bob Hope.
Among the toys Nicki and Alex play with in Japan is an Alien Baltan figure. Tokusatsu fans will remember him from the popular Ultraman franchise, created by Eiji Tsuburaya, who was also one of the creators of Godzilla(who is mentioned in dialogue)
