Though the wearing of white garments and other formalities of the special mourning, called imi, cease at the end of fifty days at the longest, bright colors are not to be worn, or a Shintō temple to be entered, for thirteen months, and this is called _buku_. For a husband, imi lasts thirty days and buku thirteen months; for a wife, imi twenty days and buku three months; for grandparents and uncles, the periods are thirty days and five months; for an eldest brother or sister, or aunt on the father’s side, and great-grandparents, twenty days and three months; for great-great-grandparents and aunts on the mother’s side, fathers and mothers-in-law, brother-in-law or sister-in-law, or eldest grandchild, ten days and one month; for other grandchildren, and for cousins of either sex, and their children, three days and seven days. For children under the age of seven years, whatever the relationship, there is no mourning. The great dignitaries must wear mourning for the Shōgun; all officers, civil and military, for their princes; and whoever derives his subsistence from another must mourn for him as for a father. Pupils also must mourn for their teacher, education being esteemed equivalent to a livelihood. The sons of a mother repudiated by her husband and expelled from his house mourn for her as if dead. In case of persons holding office, who die suddenly without previously having resigned in favor of their heirs, it is not unusual to bury them the night after their death, in a private manner. The death, though whispered about, is not officially announced. The heir, who dresses and acts as usual, notifies the authorities that his father is sick and wishes to resign. Having obtained the succession, he soon after announces his father’s death, and the formal funeral and mourning then take place. The honors paid to deceased parents do not terminate with the mourning. Every month, on the day of the ancestor’s decease, for fifty, or even for a hundred years, food, sweetmeats, and fruit are set before the ihai. One hundred days after the decease of a father or mother, an entertainment is to be given to all the intimate friends, including the priest who presided at the funeral. This is to be repeated a year from the death; and again on the third, seventh, thirteenth, twenty-fifth, thirty-third, fiftieth, hundredth, and hundred and fiftieth anniversary, and so on, as long as the family exists. To secure the due payment to themselves of funeral honors, those who have no sons of their own adopt one. If any accident, fortunate or disastrous, happens to the family, it is formally communicated to the ihai, such as the birth of a child, a safe return from a journey, etc. In case of floods or fires, the ihai must be saved in preference to everything else, their loss being regarded as the greatest of misfortunes.
