The Mikata Five Lakes exhibit varying colors due to different depths, mineral content, and salinity levels, ranging from freshwater to saltwater.
Lake Suigetsu contains 'varves,' which are annual sediment layers that provide a continuous, high-resolution climate record dating back 70,000 years.
The Rainbow Line toll road, which provides the only vehicle access to the terrace, was originally opened in 1968.
The terrace is officially recognized as a 'Lovers' Sanctuary' in Japan, a designation given to romantic spots with high scenic value.
The chairlift system allows passengers to experience the view without the physical barrier of a cable car cabin.
Goko Terrace is an observation facility situated at the summit of Mount Baijo, accessible via the Mikata Goko Rainbow Line toll road. The terrace offers a 360-degree panoramic view of the Mikata Five Lakes, a designated Ramsar site featuring five distinct bodies of water with varying salinity levels. Visitors reach the summit platform by cable car or chairlift from the base station. The facility includes a designated 'Lovers' Sanctuary' monument and multiple landscaped viewing decks. The five lakes consist of Lake Mikata, Lake Suigetsu, Lake Suga, Lake Kugushi, and Lake Hiruga. The site is part of the Wakasa Wan Quasi-National Park system. The observation deck is constructed of wood and glass to minimize visual obstruction of the horizon. Walking paths connect various viewpoints along the ridge of the mountain.
The central glass-fronted viewing deck that provides a clear line of sight encompassing both the Japan Sea and the five lakes simultaneously.
Bring a windbreaker, as the summit elevation causes significantly cooler temperatures and higher wind speeds than at sea level.
Visit the footbath on the terrace to rest while viewing the lakes.
Check the weather radar specifically for Mount Baijo before traveling, as fog frequently obscures the lakes.
Do not rely on the view during heavy rain or thick cloud cover, as the lakes become completely obscured.
May close temporarily during severe weather events or high winds.
