Sanbondake is a drift dive site located off Hachijojima, Japan, characterised by a shallow profile ranging from the surface to 13 metres. The site is defined by strong currents that necessitate advanced drift diving skills. Divers must access the site by boat and maintain close proximity to the dive leader to manage water movement safely. Visibility at the site typically ranges between 10 and 25 metres. Water temperatures fluctuate throughout the year, from a low of 19 degrees Celsius in February and March to a high of 27 degrees Celsius in August and September. Due to the significant current, careful planning with a local boat operator is essential.

Okubo Hama is a shore-entry reef site located on Hachijojima, Japan. The site reaches a maximum depth of 14 metres and offers visibility that can extend up to 30 metres. With mild currents, it is suitable for beginner divers and snorkellers. The topography consists of reef structures that require careful buoyancy control to avoid contact. Due to the presence of sharp coral and rocks, protective footwear is recommended for shore entries. Divers and snorkellers should remain mindful of their surroundings to prevent injury from the reef structure while exploring the area.

Zenisu is an offshore seamount located off the Izu Peninsula and Hachijojima, Japan. This drift dive site is situated in open water and is characterised by strong, consistent currents. The topography ranges from 8 to 18 metres in depth, with an average of 12 metres. Due to the exposed nature of the seamount and the potential for powerful water movement, this site is strictly for advanced divers with solid buoyancy control. Boat access is required, and divers must coordinate closely with their operator to manage entries and exits safely. Conditions can shift between dives, and there is no shelter or shore support available at this location.

Kamene is a drift and reef dive site located off the Izu Peninsula, reaching depths of 24 metres. This site is strictly for advanced divers due to the strong, relentless currents that frequently occur. Access is by boat only, and the site requires solid buoyancy control and drift diving experience. Water temperatures fluctuate between 18 and 26 degrees Celsius throughout the year. Divers must remain close to the boat entry point and maintain contact with their group during all phases of the dive. Because current strength and visibility can change rapidly, it is essential to check current tables and confirm conditions with your operator before departure.

A Point is a reef dive located off the Izu Peninsula, Japan, reaching depths of 21 metres. This boat-accessible site is suited for intermediate divers due to moderate currents and consistent surge. Visibility typically ranges between 10 and 25 metres. The reef structure supports a variety of temperate marine life, including reef fish and invertebrates common to the region. Water temperatures fluctuate from 18C in winter to 27C in summer, requiring appropriate thermal protection. Divers should monitor conditions closely for surge and swell activity, which can intensify around the reef, and manage buoyancy accordingly throughout the 50-minute dive.

Jabune is a drift dive site located off Hachijojima, characterised by strong currents that dictate the dive profile. The site extends from the surface to a maximum depth of 22 metres. Due to the significant current strength, this location is suitable only for advanced divers. Access is exclusively by boat, and divers must coordinate their drift vector with the skipper prior to entry. Conditions can shift rapidly between dives, and visibility is variable. Divers should remain aware of their depth and maintain caution regarding dangerous marine life during all boat entries and exits. Facilities at the site are limited, so confirm all necessary safety equipment with your operator before departure.

Budaine is a drift dive located off the Izu Peninsula, Japan, characterised by strong currents that require advanced diving skills. The site reaches depths of 24 metres and is strictly a boat-access location. Divers should be prepared for shifting conditions and must maintain confident buoyancy control throughout the dive. Due to the nature of the current, it is essential to carry a surface marker buoy and deploy it early during ascent to ensure visibility to the boat crew. The site supports a variety of marine life typical of the region's habitat, including various reef fish and invertebrates.

Enokuchi is a drift dive site located off the Izu Peninsula, Japan, characterised by strong currents and open water conditions. The site reaches a maximum depth of 23 metres, with visibility typically ranging between 20 and 30 metres. Due to the significant current and the presence of shark species, this site is strictly for advanced divers. Access is by boat only, and divers must coordinate closely with their skipper regarding current timing and surface signalling protocols. Water temperatures fluctuate between 18 and 26 degrees Celsius throughout the year. Divers should maintain strict buoyancy control and monitor their depth gauges closely while navigating this dynamic marine environment.
