Mikami Museum and Japanese Gardens’ cultural director Tom Gregersen will be stepping down from full-time exhibit curating and cultural guidance of the organization after 35 years of service. Before he says “Sayonara,” however, he would like to share some favorite objects from the museum’s treasure vault with the audience that has graciously supported his efforts orover the decades. Some objects will be seen for the first time, while others are old friends. All reveal a culture that is dynamic, design-conscious, and imaginative.
