Here's something remarkable: the lotus traces its origins all the way back to the age of dinosaurs, making it one of the most ancient flowering plants on Earth. Even more astonishing are the 'ancient lotus' specimens — flowers that have blossomed from seeds roughly 2,000 years old. The more you learn, the more romantic this flower becomes.

In this guide, we explore the unique characteristics of the lotus, the fascinating story behind ancient lotus varieties, and the best spots across Kanagawa to admire them. As the summer heat intensifies, why not rise a little earlier one morning and seek out these water-borne wonders?

What Exactly Is a Lotus?

The lotus is an aquatic plant and one of summer's most iconic flowers. Around July, its stems shoot upward, producing large white or pink blossoms that hover about a metre above the water's surface. The blooms last a mere four days before the petals fall, leaving behind the distinctive seed pod (lotus receptacle) dotted with small holes — each one cradling a seed that will prepare the next year's display.

Lotus vs Water Lily: How to Tell Them Apart

Often confused with the lotus, water lilies also produce similar white and pink flowers on the water. Look closely at the leaves, however, and the difference is unmistakable. Lotus leaves stand tall above the water on rigid stalks — known as 'standing leaves' — while water lily leaves float flat on the surface. Lotus leaves are round and unbroken; water lily leaves have a distinctive deep notch.

A Flower That Outlived the Dinosaurs

Lotus leaf fossils have been discovered in Cretaceous-period strata — meaning these plants bloomed while dinosaurs still walked the Earth. The 'ancient lotus' phenomenon brings this deep history vividly to life. These are flowers grown from seeds that lay dormant underground for millennia before being successfully germinated in modern times. The most famous example is the Oga Lotus (Oga Hasu): in 1951, botanist Dr Ichiro Oga successfully germinated a lotus seed estimated to be around 2,000 years old, unearthed from a geological layer in Chiba Prefecture. The following year, it produced a delicate pink blossom to worldwide fascination. When that seed first settled into the earth, Japan was still in the Yayoi period.

Where to See Ancient & Oga Lotus in Kanagawa

Kanagawa boasts several spots where you can experience the weight of botanical history firsthand. At Kanigaya Park you'll find ancient lotus varieties, while the moat of Odawara Castle and the Yokohama Children's Botanical Garden showcase the celebrated Oga Lotus. Different locations offer different varieties — a perfect excuse to explore.

Temples & Shrines: Kanagawa's Living Lotus Sanctuaries

Rooted in mud yet producing pristine blooms and abundant seeds, the lotus has been cherished for centuries as a symbol of purity and vitality. This is precisely why the flower became a fixture in temple and shrine gardens, where it continues to adorn summer ponds to this day. Kanagawa is dotted with sacred sites where historic architecture and lotus blossoms create truly unforgettable scenes — especially in the early morning hours when the flowers first open.

Kanagawa's Lotus Varieties: A World of Diversity

Including cultivated varieties, there are said to be several hundred lotus types worldwide, each with distinct petal counts, colours and patterns. Kanagawa alone offers a remarkable diversity — so keep your eyes peeled for the subtle differences as you explore.
