Japan has a number of unique ways to celebrate the new year, and one of them is hatsuhinode, or watching the first sunrise. The Kobe Nunobiki Herb Gardens plan to open at 6 am on New Year's Day, allowing visitors to enjoy the sunrise from several great vantage points on the grounds. They recommend either the first or second floor terraces as prime sunrise viewing spots.
Something to keep in mind if you plan to visit is that the sunrise may not be visible if the weather conditions aren't clear – so factor that in and check the forecast. Sunrise in Kobe for January 1st is at 7.06 am.
