The optimal visiting period is from mid-June to early August when water lilies are in full bloom, though lilies generally flower from May through October. Early summer and fall are considered the best seasons, with fall offering vivid red Japanese maples surrounding the pond. Early morning visits provide the calmest water conditions and soft lighting, while sunny afternoons make the koi most vibrant and the water sparkle. Heavy rain can cloud the pond water for approximately two days, so check weather conditions before visiting.
