Today is the last day of 2017. In Japan, the last day of the year is called "Omisoka". Preparing for the New Year's Day before Omisoka and waiting for the coming new year are the basic way to celebrate the such festival.
In the deep of Omisoka night, before the New Year comes, all the temples in Japan will toll the "Bell of New Year's Eve". Why they must toll such bell? Now let me introduce to you such kind of culture only Japan has.
About 108, there are various explanations. One of the two main versions comes from yoji jukugo "Shikuhakku"（4×9＋8×9＝108）;the other version is that the people's desire and chaotic state of mind are brought by 6 sensory organs. And these 36 kinds of troubles which can be perceived are multiplied by 3 time axes of past, present and next life, then we get 108.
Best wishes for a wonderful year.
