Yumenoshima Tropical Plant Dome | What Brought Me Here: The Strange and Gigantic Rafflesia

I visited in late February 2025. The image shows part of the exterior of the Yumenoshima Tropical Plant Dome. The building consists of three domes, with additional domes flanking the one in the photo. Standing in front of the facility, the full panorama of the domes stretching before you is truly impressive.

Even before entering, your eyes are immediately drawn to the towering, top-heavy palm trees that command attention. Their striking shapes are reminiscent of enormous bird’s nests, and simply gazing up at them makes you feel as though you’ve been transported to a foreign sky. Next to the dome, there is also an herb garden where a wide variety of herbs are cultivated.

It’s the perfect spot for anyone looking to enjoy a taste of the tropics. As a monstera enthusiast, my eyes were naturally drawn to the lush green monstera wall. The countless rope-like strands hanging down are likely aerial roots. The monstera wall forms a walk-through tunnel behind a waterfall, and personally, I think the area around this waterfall is the highlight of the entire facility.

My reason for visiting wasn’t simply a love of tropical plants. The trigger was the flower in the image below.

In a previous post, I shared a photo book by photographer Aiko Tomiyama. In the section featuring Mount Kinabalu in Malaysia, there was a note that read: “A Rafflesia flower can be found in the sea of trees within Kinabalu Nature Park.” No photo of the flower was included, but the text described it as “the world’s largest flower, measuring 30 to 100 cm in diameter, which emits a foul odor when in bloom.” Curious about how the world’s largest flower could possibly smell so terrible, I searched online — and discovered that this very Rafflesia could be seen at this tropical plant dome. That’s what brought me here.

As it turned out, the flower in the image above was a replica. According to my research, Rafflesia relies on flies for pollination, and it has evolved to mimic the appearance and texture of rotting flesh — complete with a foul odor — in order to attract them. What’s more, despite its enormous size, it is a parasitic plant, which is equally astonishing. It is also said to make a sound similar to splitting cabbage when it blooms. In both appearance and behavior, it is truly a flower like something out of folklore.

This has been just a brief introduction focusing on the monstera waterfall and the Rafflesia, but the Yumenoshima Tropical Plant Dome is a spacious facility with much more to offer — from areas dense with diverse tropical plants to a café and various other sections.
