Halloween Night in the Forest is an annual autumn night illumination event in Shinrin Park, also known as the Musashi Kyuryo National Government Park. It is the first of three illumination events the park holds each year. Unlike the autumn illumination event that is held in November, this event is only held on weekends and public holidays. It is particularly popular with families thanks to the Halloween decorations.
Half a million lights are used for the Halloween themed illumination, and there are also large pumpkins displayed around the central gate. The illumination stretches for about a kilometer from the central gate to the arboretum. The central gate and central gate parking extend their hours for the occasion, but all other gates are closed at regular closing hours. In an 'usual' year they run several other events during the period of the illumination. However, in 2020, on account of the Coronavirus pandemic, they do not have any additional events such as workshops or face painting.
The event itself is free, but adults have to pay to get into the park (¥450). Children can enter the park for free.
