Hitachi Seaside Park West entrance is the favorite check-in spot of visitors

Located in Ibaraki Prefecture, the northeast of Kanto region, Hitachi Seaside Park Japan (国営ひたち海浜公園, Kokuei Hitachi Kaihinkōen) is touted as the most popular public park in Japan. The park covers a long coastal line and an area of 350 hectares which is divided into several distinct areas: Miharashi area, West Entrance area, Forest area, Grassland area, and so on. 

Hitachi seaside park is obviously an inspiring landmark for nature lovers. It features vividly green space and a wide range of seasonal flowers. The park’s most iconic flower is baby blue eyes (Nemophila), with the blooming of 4.5 million of the translucent-petaled blue flowers during spring. In fall, the hill will be covered by summer cypress (Kochia) which slowly turn red as the weather turns cooler. Along with that, paths crisscrossing the hill provide breathtaking views over the Pacific Ocean.

The park is iconic for its Miharashi Hill, a gently sloping hill filled with green kochia plants

Although seasonal flowers are highlights, visitors to the parks can enjoy a variety of intriguing outdoor activities. There is a small amusement park with a ferris wheel, walking trails through the extensive Hitachinaka Nature Forest, while the Dune Garden showcases plants native to the coastline of Japan. The park is quite a nice place to visit as a day trip from Tokyo, and it’s not surprising to see a big crowd over the weekends.

Best time to visit

Late March to Mid April 

At this time of the year, you will have chance to take brilliant pictures with Narcissus flowers. These gorgeous yellow blooms are not originally cultivated in Japan but imported to this country in the early 1990s. They have slowly become acclimated to the Japanese weather conditions, and now popular with more than a million blooms every spring at the Hitachi Seaside Park. 

Its bright yellow hue will cheer up anyone!

Mid April to Late April 

The tulip season at Hitachi Seaside Park is pretty short in comparison to other types of flowers, but when it happens, it’s quite a sight to behold. Unlike most flower gardens, rather than blooming in just one colour, the tulips are planted to bloom like a rainbow across the entire park. Thousands splash of colors, from red, orange to yellow, purple combine together to create the most incredible backdrop. 

Despite happening during the time there the famous Japanese cherry blossoms are blooming across the entire country, tulip season is still something to keep in mind

Early April to End of May 

This is what you definitely can’t miss. 4.5 million blue nemophila flowers bloom at the 3.5-hectare Miharashi Hills and transform the field to the never-ending blue ocean. You’ll feel like you’re diving into the ocean of flowers! During this period, expect to see hundreds of people in the crowd who pretty much want the same thing as you – an epic photo opportunity of the stunning blooms.

Miharashi Hills are located at 58 m above sea level, offering an amazing panoramic view of the flowers, blue sky and the ocean, all in blue

Mid of July to Late September 

Arguably the second most popular period to visit the Hitachi Seaside Park would be during summer for the Kochia (summer cypress). 32,000 Kochia balls are planted at the miharashi Hill in June, and grow their size from 15 cm to 70–80 cm during summer. They start off as bright green in July, and gradually change colour to become a deep vibrant red by the end of October, before slowly becoming a burnt colour, just in time for autumn. At the peak season, there will be an event “Kochia Carnival” held annually in which the entire park lights up after dark with colourful LED lights.

In addition to kochia balls, cosmos flowers are in full bloom from early to late October, and fields are next to each other! Don’t miss capturing some photos with those cute and colourful plants!

October is the time for many other beautiful flowers like baby pink cosmos and white Nippon Daisies
