As of late April 2026, Hitachi Seaside Park in Ibaraki, Japan, features its annual, stunning display of 5.3 million Nemophila (baby blue eyes) flowers covering Miharashi Hill. The flowers, which peak around late April, create a “sea of blue” that blends with the sky and ocean, offering a popular, picturesque springtime scene.
- Location: Miharashi Hill inside Hitachi Seaside Park, Ibaraki Prefecture, Japan.
- Flower Type: Nemophila menziesii (baby blue eyes), a 2-3 cm wide, light blue flower native to California.
- Peak Bloom: Typically mid-April to early May.
- What to expect: The flowers turn the entire hillside into a “soft blue” landscape.
- Accessibility: Accessible via a ~80-minute train ride from Tokyo to Katsuta Station, plus a bus ride.
The phenomenon is so popular that the park sells unique blue-themed treats, such as “blue ramune soda soft serve” ice cream, during the peak season.
