On the Fukushima Prefecture side, there are two access points: at the Numayama Toge Pass and Miike. Ozeguchi is on the Niigata Prefecture side, and Kuriyamaguchi is on the Tochigi Prefecture side.
Q1-6 When is the best time for skunk cabbages, daylilies and autumn leaves?
Although the exact timing varies from year to year, skunk cabbages are best between late May and early June, daylilies are best between mid- and late July, and autumn leaves are best in early October. Oze is crowded on weekends during these seasons, and visitors may find it harder to enjoy the area’s charms in a leisurely way.
In addition to these flowers and landscapes, Oze has diverse natural attractions that change on a daily basis. The Oze Preservation Foundation hopes that visitors will enjoy these wide-ranging landscapes to the maximum by visiting again.

Q2. Entering Oze
Q2-1 I’m not physically strong. Will I be OK?
There are trailheads with gentler gradients, such as at the Hatomachi Toge and Numayama Toge passes. Please plan hiking reasonably in consideration of your physical capacity.
Q2-2 Can I visit and return in one day?
Yes. Many people come to Oze for day trips; however, this allows only a short time in Oze considering the time taken to get here and back. Staying near or in Oze the night before a hike enables visitors to enjoy the area at a more leisurely pace. Mornings and late afternoons in the region are also quite beautiful.
Q2-3 Can I bring pets with me?
Please do not bring pets, as they may disturb local wildlife.
Q2-4 Are there any places that are dangerous for children?
Walking on the boards in the wetlands is basically safe; however, the boardwalks are elevated in some places and can be very dangerous if you lose your footing. Please be careful with small children.
Also, alpine areas such as Mt. Shibutsu have steep slopes in some places, and care should be taken.

Q3. Necessary items
Q3-1 Can I wear sports shoes?
Although it is possible to negotiate Oze’s boardwalks in sports shoes, we recommend trekking shoes with a good grip as wet boardwalks can be very slippery.
Q3-2 Can I rent shoes at the trailheads?
There are no shoe rental facilities, but some rest stops sell footwear. However, Oze is an alpine area, and we encourage visitors to bring their own mountain shoes.
Q3-3 Is cold-weather clothing needed in summer?
Even in summer, temperatures can be quite low in the morning and late afternoon, and the same-day temperature fluctuation is very large. We recommend bringing warm clothing.
Q3-4 Are raincoats needed even if the weather forecast is good?
The weather can be changeable in Oze, and may turn adverse even if conditions in surrounding areas are fine. Getting wet without a raincoat can cause rapid body heat loss. Oze is a mountain region, so a simple raincoat may not offer adequate protection from rain in windy conditions; we recommend bringing separate rainwear for the top and bottom halves of the body.
