Toneri Park, located in Adachi Ward, Tokyo, is home to fields of nemophila that cover the park each spring. The tiny blue flowers bloom all over the area, creating a view that looks like a blue carpet, which has made this a popular spot for photography. Nemophila is usually at its best from mid-April to early May. Around this time, visitors can sometimes enjoy the sight of cherry blossoms together with the blue flowers. Thanks to its wide grass areas and walking paths, the park is also a pleasant place for a spring stroll or picnic.
