In my recent visit to the shrines and castles of the Japanese cities of Osaka and Kyoto, I noticed that elementary pupils, in groups of five to 10, were being guided not just by their teachers but also by elderly persons who appeared to be explaining to them the history or the significance of the places we were visiting. I, of course, assumed that was what the older guides were doing as they gesticulated vigorously while talking (in Nihongo, I suppose). I believe this is how elementary educational field trips should be conducted—focused and in small groups, especially if they involve young and impressionable kids.
