Onuma Park

Updated June 21, 2025

Description

Onuma Park is a dreamy outdoor paradise that honestly blew me away when I first visited. Located in Hokkaido, this natural wonderland spreads across a landscape dotted with crystal-clear lakes and backdropped by the majestic Mount Komagatake. The park’s most striking feature? The stunning volcanic islands scattered throughout its lakes – I counted 126 of them last time I was there! Each one is like a tiny green jewel floating on the water’s surface.

Key Features

• Two main lakes: Onuma and Konuma, connected by narrow channels that create perfect spots for kayaking
• A 25-kilometer network of walking paths and bridges linking various islands
• Rich bird-watching opportunities (I spotted at least 5 different species of waterfowl on my last visit!)
• Year-round fishing spots where you can catch fresh-water fish
• Mount Komagatake’s iconic silhouette providing picture-perfect photo opportunities
• Winter ice fishing when the lakes freeze over (trust me, it’s an unforgettable experience)
• Cherry blossom viewing spots in spring, particularly magical around the lakeside
• Dedicated cycling routes that wind through the most scenic parts of the park

Best Time to Visit

Each season brings its own magic to Onuma Park, but I’d say late spring through early fall offers the most pleasant conditions. May through June is particularly spectacular – the weather’s just right, and the surrounding mountains are painted with fresh greenery. Fall brings an explosion of autumn colors that reflect beautifully in the lakes. Y’know what’s cool? Even winter has its charm, with ice fishing and snow activities taking center stage. Just bundle up properly – those Hokkaido winters can be pretty intense!

How to Get There

Getting to Onuma Park is actually pretty straightforward. The most convenient way is taking the train to Onuma Koen Station – it’s right there on the JR Hokkaido Line. From Hakodate, it’s about a 45-minute train ride, and you can use your Japan Rail Pass if you’ve got one. Once you arrive at the station, the park’s main attractions are just a short walk away. During peak season (June to September), there’s also a handy shuttle bus service that runs from major nearby cities.

Tips for Visiting

Okay, here’s what I learned from my visits – and believe me, I wish someone had told me these things before my first trip! Bring comfortable walking shoes because you’ll want to explore those island paths. Pack a camera – the views are incredible, especially during sunrise when the lake mirrors Mount Komagatake perfectly. If you’re into cycling (which I totally recommend), you can rent bikes near the station. They’ve got regular bikes and electric ones too.

Bring cash! Some of the small food vendors and rental shops don’t accept cards. Speaking of food, try the local specialties at the small restaurants around the park – the fresh-caught fish dishes are amazing. In summer, don’t forget insect repellent – those mosquitoes can be pretty enthusiastic. And if you’re visiting in winter, dress in layers because temperatures can drop significantly.

Oh, and here’s a pro tip: arrive early in the morning if you want to avoid the crowds and catch the best light for photos. The park gets busy around mid-morning, especially during peak season and weekends. Last but not least, check the weather forecast before you go – the park’s beauty really shines on clear days when Mount Komagatake is visible.

I’d recommend setting aside at least half a day to properly explore the park, though you could easily spend a full day here if you want to try activities like boating or cycling. And don’t rush – part of the park’s charm is in taking your time to soak in the peaceful atmosphere and discover your own favorite spots among the islands.
