heisei no mori rose tunnel saitama roses

Heisei no Mori – or Heiseinomori – is a park in West Saitama in a town that has recently become better known, due to its exit on the Ken-o Expressway.  Kawajima town, also referred to as Kawashima town,  is beside the cities of Sakado, Kawagoe,  Higashimatsuyama and Okegawa. The park has started to make its mark and become more popular and famous due to its claim on having the longest rose tunnel in Japan. And it is one of Saitama’s rose flower viewing spots.

Japan’s longest rose tunnel

The rose tunnel is 330.5 metres long. 日本一長いバラのトンネル. Their annual park festivals are also becoming more known and popular in the last few years. The wading pool and river is often listed in summer travel magazines for kids, adding to it’s increasing popularity. The drive-thru Starbucks I pass on route, is an added attraction for me.  However, lack of public transport to the park and it’s distance from a train station ensures that the park is never too crowded.

In 2020 the rose tunnel was closed to the public during the State of Emergency. The car park was also closed. It remains to be seen whether the rose tunnel will be open in 2021. If there is no State of Emergency it will most likely be open. Even if it is not you can view the roses from outside the tunnel. The car park was not closed during the Winter 2021 State of Emergency, so it is unlikely the car park will be closed again. However, the wading river will probably not be open again in 2021.

Saitama Roses

Inamachi is most famous for roses in Saitama. There are several other places you can view roses in Saitama though, including the rose tunnel at Heiseinomori. Some Saitama rose locations that feature on this blog include: Yono Park roses, Greenfinger Cafe in Tsurugashima, Garden Cafe Greenrose in Moroyama, and Takinoiri Rose Garden.

The park has some yaezakura, late blooming cherry blossoms. They bloom around mid April. There are also lotus that bloom around mid June to early July. See the next paragraph for iris information. There are even more seasonal blooms in a community field beside the park. That field allows picking toward the end of bloom for each flower. That field – Yatsubayashi community field – grows rapeseed in spring, sunflowers in summer and cosmos in autumn.

The Iris of Heisei no Mori

There are approximately 2,600 iris flowers in Heiseinomori park. Iris is the flower of Kawajima Town. The iris in the park are of the “hanashobu” variety, specifically Edo Hanashobu, Ise Hanasobu and Higo Hanashobu. The Edo Hanashobu bloom is horizontal, the Ise Hanashobu are pendent and the Higo Hanashobu type are arched. The Japan Iris organization website has detailed information in English about these varieties of iris. Heisei no Mori iris are shades of white, purple and yellow.

Heiseinomori park has a large playground with combination equipment including, but not limited to, a long slide, climbing walls and nets, and smaller slides. There is also a sandpit, spring rides, a flying fox and a smaller combination unit for young children.  Beside the rose tunnel there is also a small playground for younger children. There is no shade in the large playground and limited shade in the small playground. However, they also have a particularly nice splash pool and wading river,the latter of which is shaded in many parts.The wading river starts running at the weekends first, during the month of May and eventually is available daily.

There is no restaurant or shop on the premises, but there is a cafe at one exit of the park. The park also has a library and public hall beside it. There are 3 toilets in the park.  Parking is free.  The park holds three annual festivals. One on boys day, May 5th, one toward the end of May in celebration of the roses, and one on the 23rd of November.  Apart from the rose garden, there is a lotus pond and many flowers including the flower of Kawajima town, the Iris Ensata. The park is quite pretty throughout the seasons.  You will see artists and photographers alike capturing the beauty of the flowers in this park.  There are some sporting facilities in the park including a running track, soccer field and fishing.

In 2019 they merged them into one that happens in mid May. There is a really popular fish catching event at the festival. Kids get into the pond and catch fish with their hands. There are also other children focused events you can enjoy on the day. You can read detailed information about the festival here:

There is light up in the park in winter too, in the form of night illumination.
