Minamijima is a small, uninhabited island located south of Chichijima in the Ogasawara Islands, designated as a natural monument of Japan. It is renowned for its exceptional natural beauty, featuring unique geological formations like the rock gate at Ogi-ike beach, transparent waters, and a distinctive brackish water pond. Its significance lies in its pristine, untouched ecosystem, which is carefully preserved through strict access regulations.
Visitors consistently rave about the island's stunning beauty, often describing it as "absolutely stunning" and "very beautiful." The hidden beach, panoramic views of other islands, and the unique swimming holes are frequently highlighted as memorable experiences. Many reviewers emphasize the unique opportunity to see white-tip reef sharks while snorkeling, adding an adventurous element to the visit. The strict rules for preservation are also appreciated by visitors, who recognize their importance in maintaining the island's natural state.
To visit Minamijima, it is mandatory to join a certified tour with a guide, as access is limited to only 100 people per day. Reviewers strongly advise taking motion sickness medication, as the boat ride can be very rough. It's crucial to bring a camera to capture the incredible scenery, as several visitors regretted not having one. The island is typically closed to visitors from November to February for preservation, so planning your trip during other months is essential. While the island itself doesn't require extensive time, the journey and associated activities like whale watching or snorkeling mean a half-day or full-day excursion is common.
Reaching Minamijima requires first getting to Chichijima in the Ogasawara Islands. This involves a 24-hour ferry journey from Tokyo. Once on Chichijima, you must book a tour with a certified guide, as direct access to Minamijima is not permitted. These tours typically depart from the main port on Chichijima and involve a boat ride to the island. Given the remote location and the need for a guided tour, independent travel directly to Minamijima is not an option.
A common complaint, or rather a challenge, is the difficulty and time commitment involved in reaching the Ogasawara Islands and then Minamijima itself. The long ferry ride to Chichijima can be arduous, and the boat trip to Minamijima can be very choppy, leading to seasickness. Mitigate this by taking motion sickness medication well in advance and choosing a tour operator known for comfortable boats. Additionally, the strict access rules and seasonal closures mean visitors must plan their trip carefully and book tours far in advance to secure a spot.
