Kanazawa-Jo Castle park
1-1, Marunouchi, Kanazawa
You can enter this park for free, although the museum has an entry fee. Sakura bloom all around the castle, and you will see some families enjoying lunch during the daytime. Have your picnic on the lawn or on a bench! Check the underneath of the Ishikawa-Mon gate, that's one of the party spots for night Hanami called Chinsho-En. People put their own blue plastic mat to keep their space, which means those are already reserved!
