When is the blue flower season at Hitachi Seaside Park? (Mid-April 2025!)

When it comes to spring in Japan, most people immediately think of cherry blossoms. The short-lived flowers are an iconic phenomenon, but there’s one place near Tokyo that boasts equally breathtaking spring scenery: Hitachi Seaside Park! This coastal attraction is home to some of the most expansive flower fields near Tokyo.

In 2025, the two-week-long Nemophila season is expected to peak from around April 17-25.

Nemophila is a flower of the forget-me-not family originally native to North America. It is known for its beautiful blue blossoms during spring, where its common name of “baby blue eyes” comes from.

Hitachi Seaside Park in Ibaraki Prefecture is known for its vast fields of these flowers and draws in visitors from all over Japan and all around the world every spring. A JR express train followed by a bus takes you there in around 1.5 hours.

Especially beautiful is Miharashi Hill, where around 5.3 million individual nemophila create scenery that looks like the sky is melting into the land. The hill is about a 15-minute walk from the park’s west gate, and its flowery gloriousness can be enjoyed from mid-April to early May.

Next to the Nemophila flowers, rape blossoms and old, traditional houses are the main highlights of Miharashi Hill.
