When to Visit
Below gives you information and a rating of the best time of year to visit.
January
Winter casts a quiet charm over the Kii Peninsula, with crisp air and occasional snowfall dusting the peaks of the Kumano mountains. Pilgrims embarking on the Kumano Kodo trails enjoy a peaceful, mystical atmosphere, free from the summer crowds. In Nara, temple visits are particularly atmospheric, with hatsumode (New Year’s shrine visits) bringing a spiritual energy to Kasuga Taisha and Todaiji. Down the coast, Shirahama Onsen provides a welcome escape, with its steaming outdoor baths offering ocean views.
February
Late winter sees the Setsubun Mantoro Festival in Nara, where thousands of lanterns illuminate Kasuga Taisha in a breathtaking nighttime display. Further south, in Wakayama, early plum blossoms begin to appear at Jonangu Shrine and Minabe Bairin, Japan’s largest ume grove, hinting at the arrival of spring. In the hot spring town of Katsuura, freshly caught tuna is at its seasonal best, a must-try for food lovers.
March
Plum blossoms give way to cherry blossoms, with temples and shrines across the region beginning to bloom. Yoshino, one of Japan’s most famous sakura-viewing spots, sees its first delicate pink flowers, while in Koyasan, the monastic complex remains tranquil, offering a serene retreat before peak pilgrimage season. The mild temperatures also make this an ideal time to visit the dramatic coastal cliffs of Sandanbeki in Shirahama.
April
Spring reaches its peak, with cherry blossoms draping the region in soft pink hues. Mount Yoshino is the undisputed star, where thousands of sakura trees create a breathtaking sight. The ancient shrines of the Kumano Sanzan - Kumano Hongu Taisha, Kumano Nachi Taisha, and Kumano Hayatama Taisha - are framed by floral beauty, making for unforgettable springtime hikes. Coastal cities like Wakayama see the fishing season in full swing, offering excellent seafood markets, particularly at Kuroshio Market.
May
With the arrival of fresh greenery, outdoor adventures take centre stage. The Kumano Kodo pilgrimage routes are in perfect condition for trekking, offering sweeping valley views and sacred sites along the way. In Nachi, the famous Nachi Falls, Japan’s tallest waterfall, is at its most photogenic, framed by the vibrant greens of new spring growth. Meanwhile, the Mitarai Valley in Nara provides a stunning setting for riverside walks and fresh mountain air.
June
As the rainy season arrives, temple gardens come alive with lush foliage and blooming hydrangeas. Mimuroto-ji in Nara and the Hase-dera Temple near Sakurai are among the best spots to see these vibrant flowers in full bloom. While rain showers are frequent, they enhance the atmosphere of traditional ryokan stays and onsen visits, particularly in Yunomine Onsen, a historic hot spring tied to Kumano pilgrimage rituals.
July
Summer’s heat arrives, with temperatures often exceeding 30°C. Coastal escapes become appealing, with Shirahama Beach drawing visitors to its white sands and turquoise waters. Inland, the Toro Nagashi Festival at the Kumano River sees thousands of paper lanterns floated downstream, creating a mesmerising display. In Koyasan, the cooler mountain climate offers a refreshing escape, where temple lodgings provide a unique experience of Buddhist traditions.
August
Festivals dominate the month, with spectacular firework displays lighting up coastal towns like Shirahama. The Daimonji Fire Festival in Nara sees a massive bonfire lit on Mount Wakakusa, visible across the city. For those seeking adventure, the Dorokyo Gorge, with its emerald waters and dramatic cliffs, offers a scenic boat ride through one of the region’s most stunning natural landscapes.
September
The first signs of autumn begin to appear, making it a pleasant time for cultural exploration. The Kishiwada Danjiri Festival, held in southern Osaka Prefecture, is one of Japan’s most thrilling festivals, where massive wooden floats are raced through the streets. Meanwhile, in Totsukawa, Japan’s largest village, rustic hot springs and untouched mountain scenery make for a relaxing rural escape.
October
Autumn colours begin to spread across the Kii Peninsula, transforming temple grounds and pilgrimage trails into a painter’s palette of reds and golds. Tenkawa Village, hidden in Nara’s mountains, is one of the region’s lesser-known fall foliage gems. The month also sees the Fire Festival of Yuki Shrine in Wakayama, where torches are paraded through the night in a fiery spectacle of tradition.
November
With temperatures cooling, November is one of the best months for exploring the peninsula’s natural beauty. The Koyasan Danjo Garan complex is spectacular against a backdrop of maple trees, while Doro-kyo Gorge becomes even more dramatic with its autumnal reflections. At Shingu’s Kamikura Shrine, perched on a steep mountainside, the view over the Pacific is breathtaking on crisp autumn mornings.
December
As winter settles in, the peninsula quiets down, offering a peaceful retreat. The Omisoka bell-ringing ceremonies at temples like Todaiji in Nara provide a reflective way to welcome the New Year. In the onsen villages of Wakayama, steaming hot springs offer a warming respite from the cold. Meanwhile, Katsuura Port gears up for its busiest tuna fishing season, making it an excellent time to savour freshly sliced sashimi straight from the docks.
