Enjoy a 360° view at the “Rainbow Line Summit Park,” a paradise in the sky
The Five Lakes of Mikata (Mikatagoko), located across Mihama Town and Wakasa Town in southern Fukui Prefecture, are also known as the “Five-Colored Lakes” because the surface of each of the five lakes is of a different shade of blue. The Rainbow Line Summit Park, which overlooks these lakes, is a popular spot where visitors can enjoy a vast panoramic view surrounded by 360-degree scenery. Here, we’ll introduce ways to enjoy the mountaintop park and its surrounding area.

A Gradation of Blues Created by Five Lakes
The term “Five Lakes of Mikata (Mikatago)” is a collective name for five lakes: Lake Kugushi, Lake Hiruga, Lake Mikata, Lake Suigetsu, and Lake Suga. The photo shows only a portion of the Five Lakes of Mikata, but the five lakes are scattered throughout the valleys of the low mountains as if they were scattered like jewels. However, what makes them fascinating is that even though they are so close to one another, each lake has different water quality (salinity) and depth. As a result, the blue hues of the lake surfaces vary gradually, creating a gradient effect. Because of this, the Five Lakes of Mikata are also known as the “Five-Colored Lakes.”
To the Rainbow Line Summit Park!
The Rainbow Line Summit Park is a spot where you can enjoy the Five Lakes of Mikata from above. The park is located at the summit of Mount Baijo, which towers between the Five Lakes of Mikata and the Sea of Japan, about a 20-minute drive from the Wakasa-Mihama Interchange on the Maizuru-Wakasa Expressway. If you’re coming by car, drive up the Mikata-Goko Rainbow Line Prefectural Road (closed at night) and head for the Summit Park First Parking Lot (paid parking). Once you arrive at the parking lot, first purchase your Summit Park ticket at the “Ticket Counter & Information Center” located directly in front of you. You can then ascend to the summit via cable car or chairlift.

A cable car? Or a ski lift? I can't decide which one to take!
You can choose between the cable car and the chairlift to reach the summit. The chairlift, which overlooks the Sea of Japan, is full of thrills—despite its colorful, cute appearance! On days with bad weather, we recommend the covered cable car. There are heart-shaped handrails inside the cable car, so be sure to “catch some happiness.”

- I can’t help but notice the large tanuki figures next to the cable car station. Apparently, they’re “Katchan” and his family, characters from a local folktale. I had my picture taken with them.

Stunning views everywhere you look! You’ll be mesmerized by the sweeping panoramic views
Upon reaching the summit, all you see is blue in every direction. In fact, I’ve heard that the “Rainbow” in Rainbow Line comes from the concept of “seven shades of blue.” It refers not only to the five shades of blue in the Five Lakes of Mikata, but also to the blue of the Sea of Japan and the sky—making seven shades in total. You’re truly surrounded by a breathtaking blue panorama. What a luxury it is to have stunning views in every direction—360 degrees. Faced with such beautiful scenery, a smile naturally spreads across your face.
The “Rainbow Umbrellas” set up right at the lift exit are a popular feature of the summit park. Feel free to use them as you like. They’re perfect for protection from the sun or sudden rain, of course, but they also make great props for photos. Be sure to take one with you as you explore.

Romantic Power Spots to Visit with Someone Special
While strolling through the park, I came across the “Bell of Happiness.” Actually, the Summit Park is also famous as a power spot for love. Right next to the bell is “Wago Shrine,” a shrine that’s rare even in Japan because it features a “single shrine, two worship areas”—meaning you can pay your respects from both the front and the back, facing each other. They say that if a couple visits Wago Shrine together and then rings the bell once as a pair, they’ll receive even greater blessings…!?

Take a Short Break on the Stylish Terraces
After a long walk, take a break at one of the five terraces designed around the concept of “a sky terrace floating above the Five Lakes of Mikata.” In addition to the “Five Lakes Terrace,” where you can relax on large sofas, and the “Central Terrace,” which offers a beautiful view of the Japan Sea horizon, the “Wakasa Terrace” lets you try your hand at “kawarake throwing”—tossing a sun-dried clay plate (kawarake) inscribed with your wish toward the lake! I especially recommend the “Mihama Terrace.” It’s the only one of the five terraces from which you can see all five lakes. And right beneath the breathtaking view spreading out before you is—believe it or not—a foot bath! The beautiful scenery and warm foot bath will soothe away the fatigue of your journey.

In spring and fall, snap a photo surrounded by 600 rose bushes
Near the Central Terrace is a rose garden where approximately 600 roses of about 110 varieties bloom in all their glory. However, growing roses at the summit of Mt. Baijo—where weather conditions are harsh—is actually quite challenging. Thanks to the staff’s steadfast efforts, the roses now bloom twice a year, in spring and fall. When I visited for this report in early November, it was right in the middle of rose season. I was able to enjoy taking photos in the luxurious setting of being surrounded by roses with the Sea of Japan as a backdrop. The best times to see the roses are generally spring (around May 20 to June 20) and fall (around October 20 to November 20). You can check the current status of the Rose Garden at any time on the Summit Park website.

- Near the foot bath, they had towels and covers available (each for a fee) that let you soak even over your stockings! You can just drop by empty-handed—no problem.

I Want to Eat It All! Mountain-Top Park Cuisine Featuring Local Ingredients
When you visit the Summit Park, you won’t want to miss the great food. There are three dining spots in total: two at the summit and one at the First Parking Lot. All menu items are available for takeout, so please enjoy them on the terrace while taking in the spectacular views.
At “RAINBOW,” the restaurant and café in the First Parking Lot, the glass-walled interior on three sides offers stunning views, and their pizzas—made with local ingredients like Wakasa beef (Wagyu), Mihama tomatoes, and hesiko—are a hit. Since the toppings and offerings change with the seasons, you might discover new Wakasa delicacies every time you visit. You can also relax and enjoy your meal indoors, so you’re all set even on rainy or windy days.

A wide selection of original products: A souvenir shop featuring carefully curated items
Don’t forget to pick up some souvenirs! Inside “Rainbow Shop Nijiiro,” located at the foot of the mountain, you’ll find a wide array of items, including classic souvenirs from Wakasa and Mihama, popular rainbow umbrellas, a wide variety of couples’ keychains, and popular anime-collaboration Echizen washi paper—which is exclusive to this shop in the Reinan region of southern Fukui. The store manager shared their philosophy: “These are items that our multigenerational staff have all tried and genuinely believe are excellent.” Since the shop carries only items endorsed by locals, you can trust the selection. The rose corner—available only during rose season—is also worth a look. We also recommend the rainbow-colored goshuincho (temple stamp books) and the Habutae mochi in packaging exclusive to the Summit Park.

The Five Lakes of Mikata—mysterious lakes shaped by nature—offer more than just breathtaking views.
