THE new crown princess's two younger sisters, Reiko and Setsuko, were in Hongkong two months ago. But it was a closely kept secret.
They were here for a brief visit and no one wanted this turned into a media event with photographers dogging their footsteps wherever they went.
Reiko and Setsuko are twins, born on July 8, 1966.
As it transpired, no one knew who the two girls were as they shopped at the Ladies' Market in Mongkok, visited historical sites and took in what is left of Hongkong's old architecture.
The twins spent four days here as guests of the Japanese Consul-General, Masaki Orita, an old friend of the family and a diplomatic colleague of their father.
Reiko, who is with the United Nations High Commissioner for Refugees (UNHCR) and currently based in Hanoi, also visited Hongkong for a week in January, staying with the Oritas.
