Hachimantai Dragon Eye: The Mystical Melting Snowfield Eye Lake

Hachimantai Dragon Eye

Near the summit of the Hachimantai Plateau (1,613m) straddling Iwate and Akita, Kagami Pond develops a striking eye-shaped pattern each May to June as residual snow melts. This "Dragon Eye" phenomenon went viral on social media and has become one of Japan's most sought-after seasonal spectacles.

Highlights

• Dragon Eye: An iris-like pupil pattern formed as snowmelt merges into the pond
• Summit Walking Trail: Well-maintained path around Kagami Pond
• Alpine Marsh: Flat highland marshes and ponds covering Hachimantai's summit area
• Snow and New Greenery: Snow and spring green coexist in the same view

Best Viewing Period

• Late May to mid-June: Peak Dragon Eye season
• Conditions vary by year — check updates before visiting

Getting There

• From Morioka Station by Iwate Kenpoku Bus via Matsukawa Onsen to Hachimantai Summit stop: about 2 hours
• Drive to summit parking via Hachimantai Aspite Line toll road

Tips

The summit is cool even in summer — bring wind and cold protection. Best Dragon Eye photos come from the elevated section of the walking trail. Crampons recommended when snow is present.

📚 Sources

This article is based on publicly available information from Hachimantai City, Iwate Prefecture, and the local tourism association about the Hachimantai Dragon Eye (Kagami-numa), and announcements regarding travel on and the opening of the Hachimantai Aspite Line. The Dragon Eye is a natural phenomenon that changes with the progress of the snowmelt, and its peak varies greatly by year with the climate. The peak period, the Aspite Line's opening status, and the operation of the rest house and buses are subject to change, so please check official sources such as the tourism association's "eye-opening" updates and road information before you set out.

Visitor Checklist

• Estimated time: Walking to Kagami-numa just to view it takes little time, but combined with a stroll on the plateau trails or a drive, allow about half a day.
• What to bring / prepare: The elevation is high with lingering snow, so warm clothing and sturdy shoes are essential; snowy paths are slippery, so watch your footing.
• Checking the peak: The complete form is said to last only a few days, a truly once-in-a-lifetime sight. Be sure to check peak ("eye-opening") information before setting out.
• Suggested route: Starting near the Hachimantai Summit Rest House, view the Dragon Eye at Kagami-numa and also tour the maintained trails past alpine flower fields and crater lakes.
• Access notes: A road (the Aspite Line) reaches near the summit, but check its opening timing and operating status in advance.

Practical Information for Your Visit

• Opening hours (Hachimantai Summit Rest House): 9:00-17:00 (9:00-16:30 during periods when the road is closed at night). It is open from mid-April to early November, in line with the opening of the Aspite Line and the Jukai Line
• Road restrictions: The Hachimantai Aspite Line is usually closed for the winter from early November, and normally reopens in mid-April. Just after it reopens and in late autumn there is a night-time closure from 17:00 to 8:30 the following morning because of the risk of snow and icy road surfaces. Allow about 40 minutes to drive between the gates
• Time needed to reach Kagami-numa Pond: About 20 minutes on foot from the Hachimantai Summit car park to Kagami-numa Pond. Visitors are advised to come in rubber boots or non-slip shoes, as the path is snow-covered
