During the month of July, Chiba's Sakura Furusato Square will host a Windmill Sunflower Garden event. Approximately 15,000 sunflowers will be in full bloom during the event dates, including the Vincent sunflower variety named after none other than the Dutch painter Vincent Van Gogh.
Windmill Sunflower Garden will not be held in 2025 due to due to renovation work.
The renovation work is scheduled to be completed by the end of fiscal year 2028.
Admission to the event itself is free, but bring some coins if you want to pick some sunflowers -- it'll set you back ¥100 for two flowers from the picking area.
