While spring brings an array of colourful blooms including cherry blossoms, tulips and wisteria, summer is the time for hydrangeas and bright yellow sunflowers. To welcome this season’s flowers, Yokosuka Soleil Hill at Nagai Seaside Park is hosting a Sunflower Festival boasting approximately 100,000 sunflowers from mid-July to the end of August.
The sprawling yellow sunflower field stretches over 5,000sqm and has sweeping views of the blue sea. On clear days, you might even spot Mt Fuji in the distance over Sagami Bay.
The sunflowers are best enjoyed from late July to late August, with peak blooms expected in early August this year. At first glance, the sunflowers may all look the same, but you’ll be able to spot four varieties growing here: Sunrich, Sunfinity, Sensation and SunBelievable. Aside from strolling the flower fields, there is also a special food menu available until August 30. The sunflower-inspired treats on offer include doughnuts shaped as the bright yellow flower, a sunflower mango shake, sunflower mango lassi, sunflower-shaped pizza and more.
Entry is free, but if you’re driving there, parking is ¥1,700 per vehicle. Yokosuka Soleil Hill is located roughly two hours from central Tokyo by train and bus. For more information, visit the park website.
