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.

Mitsune is a challenging drift dive located off the Izu Peninsula, characterised by strong currents and depths typically between 19 and 22 metres. Due to hazardous shore breaks, boat access is mandatory for all dives. Visibility at the site ranges from 15 to 30 metres, providing clear sightlines across the underwater topography. Water temperatures fluctuate between 18C and 27C, influenced by the Kuroshio Current, with wetsuits recommended outside of summer. This site is strictly for advanced divers who possess strong buoyancy control and current-reading skills. A surface marker buoy is essential equipment for all divers here. Equipment rental is available locally.

Mikomoto Island is a small, uninhabited island located 10 kilometres off the southeast coast of the Izu Peninsula. This drift and reef site is defined by its challenging environment, featuring strong currents and shoals that have historically served as a significant navigational point. Divers typically experience depths between 20 and 35 metres, with an average of 25 metres. Due to the fierce currents and depth, this site is strictly for advanced divers. Access is exclusively by boat. Visibility ranges from 14 to 30 metres, and water temperatures fluctuate between 14 and 25 degrees Celsius depending on the season. The island is marked by the Mikomotojima Lighthouse, the oldest stone lighthouse in Japan.

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.

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.

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.

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.

Togai Beach is a rocky shore entry site located near Irozaki Port on the Izu Peninsula. This reef site serves as an accessible alternative for snorkelers when boat services to nearby areas are unavailable. The site features a scenic promenade and offers depths starting from one metre. Conditions vary, with water temperatures ranging from 18C to 28C throughout the year. Snorkelers should be aware of potential hazards including jellyfish, surf, and strong currents. The site is suitable for beginners, with a typical activity duration of 60 minutes.
