Roses lit up at night for rose light up event Heiseinomori Saitama Prefecture

Each year in May Japan’s longest rose tunnel light up their roses at night. This is an event I personally visit every year without fail. There is something about roses lit up at night that I find mesmerizing. There are plenty of roses festivals in Saitama Prefecture and beyond. But surprisingly very few of them light their roses up at night. Or if they do, its only for one or two nights. At Japan’s longest rose tunnel they light up the roses nightly for more than two weeks – starting this weekend.

Rose light up

If you are a long term reader you may remember that I used to share information annually for a rose festival at Japan’s longest rose tunnel? Unfortunately, they stopped that festival just before (and nothing to do with) the pandemic. They merged it with another festival, a children’s day festival, and created a Spring Festival instead. The spring festival is only for seven days. But thankfully the rose light up is on for more than twice that: 16 nights in total. Where exactly? Read on to find out!

Where is Japan’s longest rose tunnel?

Japan’s longest rose tunnel is located in Heisei no Mori Park in Kawajima Town (often misspelt Kawashima town) in the Hiki District of Saitama Prefecture, right beside Kawagoe. I already have detailed information on this site about the tunnel; Read more…

By train and bus – Unfortunately, Heisei No Mori is a little difficult to get to by public transport. Especially at night. Buses do going during the day, but not at night.

By car – the park is about a five to ten minute drive from the Kawajima exit of the Ken-O expressway. There is parking at the park as well as at the community center and the town hall beside the park.

There is no official event web page, but it is featured in the town’s public relations magazine.
