We came here in early July to watch the night illumination display in the lavender fields. It runs until 9:30pm. There are not only lights, but also music and bubbles. There is a bell at the top of the hill that is a very popular tourist destination for couples. The lavender fields were very beautiful and well worth it to see lit up. There are clear paved paths and no stairs, so it is easy for elderly to access. There is a parking lot but it fills up quickly and there can be a large car line to enter and exit the parking lot. Recommend parking at other places nearby and walking to the park.
In July, we were at another lavender field in the late afternoon but the evening sun had cast its shadows across the field and the colours were darkened in the shadows.
So, we drove to Hinode Park, having first checked on the Internet that the hill slope would be illuminated by the setting sun. We drove up to the hilltop at Hinode Park. Indeed, we were delighted that the setting sun lit up the lavender fields on the hill slope.
It wasn't crowded in the evening. There were a few wedding couples having their photos taken amongst the lavender fields.
