This dive site is an indoor 25-meter swimming pool located within the Bumb Tokyo Sports Culture Center in Yumenoshima, Koto-ku, Tokyo. As a controlled, artificial environment, navigation is straightforward, typically following lanes or simply enjoying open water. The facility serves as a community hub for sports and culture, offering a safe and predictable setting for aquatic activities rather than an open-water diving experience.
The pool contains no marine animals or plants, as it is a man-made, chlorinated environment. The provided description explicitly states, "You will not encounter any wild life," confirming the absence of any natural aquatic flora or fauna.
The best time to visit this indoor pool is year-round, as its controlled environment is unaffected by external weather conditions. It is ideal for individuals seeking swimming, fitness, or confined water scuba and freediving training. For divers, it offers a perfect location to practice skills, test equipment, or conduct certifications in a predictable setting before moving to open water.
