Toyama - The Northern Alps in central Japan have entered the height of their autumn colors, with the alpine landscape around Tateyama's Murodo Plateau in Toyama Prefecture offering spectacular views of red and yellow vegetation, rugged mountain ridges and the rare Japanese rock ptarmigan, a protected bird species whose survival depends on the delicate balance of the mountain ecosystem.
At an elevation of approximately 2,450 meters, Murodo Plateau in Tateyama Town has already reached its peak autumn season. The morning sunlight filters through a thin layer of mist, casting deep shadows across the mountainsides and highlighting the dramatic contours of the alpine terrain.
Hikers make their way slowly along well-maintained walking trails, surrounded by the sweeping autumn colors of the Raichozawa valley. Against the enormous mountain slopes, the small figures of visitors emphasize the scale of the landscape and the vastness of the natural environment.
For those equipped for mountain trekking, the route from Murodo Plateau toward Raichozawa offers an even closer encounter with the autumn scenery. Along the trail leading to Shin-Murodo Norikoshi, wooden boardwalks wind through alpine grasslands that have turned brilliant shades of red and yellow. The colorful vegetation beneath the feet of hikers contrasts with the mountain ridges rising in the distance, creating a landscape that rewards those willing to venture beyond the main sightseeing paths.
The area is also one of Japan's most important habitats for the Japanese rock ptarmigan, known locally as the raicho, or thunderbird.
During the second day of an observation visit, Murodo Plateau was covered in dense fog and light drizzle from early morning. Despite the poor visibility, a total of 14 Japanese rock ptarmigans were spotted, including one group of seven birds.
The species is said to have acquired its Japanese name because it frequently appears during stormy weather, suggesting that the wet and foggy conditions may actually have been favorable for observing the birds.
The Japanese rock ptarmigan is designated a Special Natural Monument of Japan and is also classified as an endangered species. According to the Tateyama Nature Conservation Center, the country's estimated population stands at approximately 1,750 birds, of which between 300 and 350 inhabit the Tateyama area, making it one of the largest concentrations of the species in Japan.
However, the birds' survival depends on a fragile ecological balance, and growing visitor numbers have raised concerns about the impact of tourism on their habitat.
Jun Kondo, director of the Tateyama Nature Conservation Center, warned that food waste left behind by visitors can attract predators such as foxes, increasing the risk to the endangered birds.
"Food scraps left behind attract foxes and other animals, and quite a few ptarmigans end up being preyed upon," Kondo said.
Leaving garbage in the mountains or stepping off designated walking and hiking trails into sensitive alpine vegetation can have serious consequences for the ecosystem. Even seemingly minor disturbances can threaten the environment that supports the birds and other mountain wildlife.
Weather conditions present another challenge for visitors. Mountain weather can change rapidly, even after periods of sunshine, while autumn brings particularly large temperature differences between daytime and the early morning and evening hours.
Koichi Nakahashi, manager of Raichoso, a mountain lodge situated on elevated ground overlooking Raichozawa, emphasized the importance of carrying appropriate equipment, including warm clothing and rain gear.
Nakahashi said the area has been attracting increasing numbers of overseas visitors, bringing welcome attention to Tateyama's natural attractions but also creating concerns about deteriorating visitor behavior.
"We are grateful that so many people are coming to visit, but..." Nakahashi said, expressing concern about tourists who fail to take their garbage home and do not observe proper mountain etiquette.
The popularity of Tateyama reflects the growing appeal of Japan's mountain landscapes, particularly during autumn when alpine vegetation transforms the terrain into a colorful panorama. However, the increase in visitors also places greater responsibility on tourists to protect the environment.
The brilliant autumn colors of Tateyama offer a striking reminder of the natural beauty of Japan's Northern Alps, but preserving that landscape and the wildlife that inhabits it for future seasons will require every visitor to act responsibly and respect the mountain environment.
