Mt. Mihara is an active volcano on Izu Oshima Island, renowned for its dramatic volcanic landscape and accessible hiking trails. It stands as the main attraction of Oshima, offering visitors a unique opportunity to explore a volcanic crater, observe lava flows, and enjoy panoramic views that can include Mt. Fuji on clear days. Its geological significance and the striking scenery make it a compelling destination for nature enthusiasts and hikers.
Visitors consistently praise the hike to Mt. Mihara as being manageable for various fitness levels, with many describing it as an "easy ascent" or "not really that tiring." The well-maintained asphalt path leads to the crater rim, with options for more adventurous gravel paths closer to the crater for better views of the lava flows. Reviewers frequently highlight the "amazing" and "beautiful" views from the top, emphasizing the unique experience of walking through a volcanic desert. The presence of English information panels along the trails is also appreciated by international visitors, enhancing the educational aspect of the visit.
For a comfortable visit, bring water and snacks, as options on the mountain are limited. Reviewers suggest spending 2-3 hours to fully explore the crater rim and surrounding areas. While the hike is generally considered easy, it can be windy at the top, so appropriate layering is advisable. Families with small children have also found the hike enjoyable, noting the gradual climb. The best time to visit is on a clear day to maximize the chances of seeing distant landmarks like Mt. Fuji.
Reaching Mt. Mihara requires careful planning, especially regarding transportation on Oshima Island. Many visitors arrive by high-speed ferry from Tokyo Takeshiba ferry terminal, a journey of about two hours. Once on the island, the most common way to reach the volcano is by bus. Reviewers advise checking bus schedules carefully, as services can be limited, especially later in the day, potentially necessitating a taxi. Some visitors also mention cycling to areas near the top. For those staying at the Oshima Onsen hotel, a gradual climb from the back of the hotel is an option. If you prefer guided tours, the Tourist Center can arrange them, with at least one bilingual guide available.
A common complaint revolves around the limited bus services, which can make getting to and from the volcano challenging without a rental car or bicycle. To mitigate this, plan your bus timings in advance or consider booking a taxi for flexibility. Additionally, some visitors have experienced poor visibility due to weather conditions, which can detract from the panoramic views. Checking the weather forecast before your visit is highly recommended to ensure the best possible experience.
