Icelandic poppies at Spring outdoor park

“Outdoor Park” is a Bi-annual event at Shinrin Park (officially Musashi Kyuryo National Government Park) in Namegawa town.

Every year Shinrin park hold two “Outdoor Park” events: one in Autumn and one in Spring. The autumn event used to be the main one with lots of stage performances and special events, but it is only on for two days on a weekend in Autumn. But the spring one is generally on for longer, during Golden Week. However, the pandemic messed everything up for the last three years! Outdoor park came back in the spring of 2023 and it is scheduled for Autumn too. However, the Autumn event is a lot more low key than before the pandemic:

Autumn Outdoor Park 2023

There are not as many free elements to this event as there used to be and there doesn’t seem to be any stage performances either. What there will be is dozens of companies, some selling food, that specialize in outdoor life. There is also some activities you can try, most of which you have to pay for. You can pay a daily rate of 1000 yen which covers bouldering, slackline, trampoline and a giant inflated play area. Adults can play too. To have a go at a bungee trampoline costs 1000 yen, for one go. The air slider is 100 yen a go. Rajicon is 1000 yen for ten minutes. They also have a robot activity for 500 yen. And treeing is finally back after four years. It costs 1500 yen. More on treeing at Shinrin Park here.

Spring Outdoor Park

The spring outdoor park was on in 2022, but events were very limited and it was only on for three days. However, thankfully in 2023 things are going back to ‘normal’. Moreover, this years spring outdoor park will actually be on for the longest to date – for seven days rather than its usual four! The spring outdoor park will be on Saturday April 29th, Sunday April 30th and daily from May 3rd to 7th in 2023.

There are different events on different days, but the activity zone is open each day. The activity zone is usually beside the park’s famous air mountain trampoline. It includes an air slider and bungee trampoline. They also have an open air market daily, with coffee, food and merchandise. This year they will also have a ‘botanical picnic’ (from May 4th to 7th). They have workshops planned too. In addition there are additional activities on select dates:

  • Treeing on April 29th and 30th
  • Canoeing on April 29th and from May 3rd to May 7th
  • Radio controlled go karts on April 29th and from May 3rd to May 7th
  • Grass skiing from May 3rd to May 5th

Last year there were quite a few rules in place in the park. However, in 2023, there is currently none listed. Normally, the Spring Outdoor Park marks the start of the water play areas opening in the park. (And in Autumn it marks the start of Halloween Night in the Forest). However, in 2022 the water play areas didn’t open until much later in the summer. Currently, they have not yet disclosed information for the water play areas in 2023.
