The Takasaki to Jomokogen route is primarily serviced by the Joetsu Line, providing a direct connection between these two locations in Japan. The Limited Express Train, known as the 'Max Toki', operates on this route, showcasing a comfortable travel experience with both Reserved and Non-reserved seating options. This service reaches speeds of up to 130 km/h (81 mph), completing the journey in approximately 1 hour and 30 minutes.
As a notable feature, the Max Toki offers spacious seating and large windows for passengers to enjoy the scenic views of the surrounding countryside. Although not classified as a high-speed train, it provides an efficient alternative for travelers wishing to explore the area.
In addition, there are some local services available, which take longer due to additional stops; however, the Max Toki remains the fastest and most direct option for reaching Jomokogen from Takasaki.
