For raise awareness of oysters which are one of the Hiroshima’s tourism resources, we utilized a brand-new media approach instead of “traditional” advertisements. We developed the “Oyster kanji workbook” as an official teaching material for elementary schools. It is a kanji workbook related to oysters and oyster's complicated kanji form. All model sentences are oyster related supervised by professors. You can practice writing oyster in kanji even 100 times. This eccentric workbook made a huge impact to media through becoming a prefecture’s certified teaching material. Thus we succeeded to make citizens and tourists have interests to Hiroshima’s oysters.
