"Koshiki Down" is a traditional event to celebrate the completion of the sake brewing season in Japan. The event is called this because the "koshiki" is the rice that is used to make the sake.
This year's sake production is expected to be higher than last year's, according to the company. The company says that the sake production will continue to grow in the coming years, despite the fact that it is difficult to get the rice to the right temperature for the sake making process.
