Wakayama is the prefecture most first-time visitors to Japan skip, and the one repeat visitors talk about most. It occupies the southern half of the Kii Peninsula — a wall of steep, cedar-dark mountains that falls straight into the Pacific — and it has been a place of pilgrimage for more than a thousand years. In October the summer humidity finally breaks, the typhoon season tapers off, and the region's oldest rituals come out of the shrine storehouses all at once. If you are planning a trip for the middle weeks of the month, this is the corner of Japan to aim for.
The headline: Mifune Matsuri at Kumano Hayatama Taisha, 15–16 October
Shingu sits where the Kumano River meets the sea, and Kumano Hayatama Taisha — one of the three Kumano Grand Shrines, and part of the UNESCO World Heritage listing for the Kii Mountain Range — holds its annual grand festival across two days.
The 15th belongs to the Shinme Togyo-shiki, a slow procession in which a sacred horse carries the shrine's spirit through the streets of Shingu. The 16th is the Mifune Matsuri itself, and it is one of the more genuinely startling things you can watch in Japan. The deity is transferred to a gilded barge on the Kumano River, and nine long, narrow racing boats — the hayabune — are rowed upstream at full speed toward Mifune-jima, a small wooded island mid-river, which they circle three times. Crews train for months. The sound of nine sets of oars hitting the water in a river gorge is worth the trip on its own.
The festival is designated an Important Intangible Folk Cultural Property. Viewing is free and happens from the riverbank; arrive by late morning on the 16th if you want a spot with a clear sightline, and bring something to sit on. Exact timings shift slightly year to year and with river conditions, so confirm with the shrine before you commit to a train.
Nachi no Dengaku, 25 October — a 50th-anniversary performance
An hour south, Kumano Nachi Taisha and Nachi Falls form the image most people carry of Kumano: a vermilion three-storied pagoda, and behind it a single 133-metre ribbon of water, the tallest uninterrupted drop in Japan. The waterfall is not a scenic backdrop here — it is the object of worship, enshrined in its own right.
On 25 October the shrine stages a commemorative performance of Nachi no Dengaku, marking fifty years since its designation as an Important Intangible Folk Cultural Property. Dengaku is a rice-field ritual dance that predates Noh; the Nachi version is normally performed only at the July fire festival, danced by masked performers to flute and binzasara — a clattering instrument made of linked wooden slats. It is also inscribed on UNESCO's Intangible Cultural Heritage list. Seeing it outside its usual July slot, in autumn light, is genuinely unusual.
Walking a piece of the Kumano Kodo
October is the best walking month of the year on the Kumano Kodo. The full Nakahechi route from Tanabe takes several days, but you do not need to commit to that. The Daimon-zaka section is the easy answer: roughly 600 metres of moss-covered stone steps climbing through cedars that are several hundred years old, ending at the stairway up to Nachi Taisha. Allow forty minutes at a gentle pace. It is the single most photographed stretch of the trail and still, early in the morning, almost empty.
If you have a full day, the Nakahechi walk from Hosshinmon-oji down to Kumano Hongu Taisha is about seven kilometres and mostly downhill — a reasonable half-day with a bus at either end.
The Wakayama City side: shrines and chrysanthemums
At the northern end of the prefecture, Itakiso Jinja holds its grand festival on 15 October and a procession on the 18th. The shrine enshrines Itakeru no Mikoto, the deity of trees, and is quiet, wooded and almost entirely free of visitors — a good counterweight to the crowds further south.
From 27 October, Wakayama Castle park hosts its 70th chrysanthemum exhibition, with a smaller display arranged under traditional paper parasols opening a few days earlier. Chrysanthemum shows are a slightly unfashionable autumn tradition in Japan and all the better for it: rows of enormous single blooms, cascade-trained plants, and the occasional figure sculpted entirely from living flowers. Entry to the park is free.
Getting there
Shingu and Kii-Katsuura are both on the JR Kisei Main Line, which loops around the coast of the peninsula. From Shin-Osaka, the Kuroshio limited express takes roughly four hours to Shingu. From Nagoya, the Nanki limited express reaches Shingu in about three and a half hours — often the better option if you are coming from Tokyo, since you can connect via the Tokaido Shinkansen. Kii-Katsuura, the base for Nachi, is about fifteen minutes before Shingu on the same line.
Local buses run from Kii-Katsuura and Nachi stations up to Nachisan (the shrine complex) and the Nachi-no-Taki-mae stop for the falls, taking twenty-five to thirty minutes. Buses are infrequent — check the return timetable before you walk anywhere. A rental car makes the whole peninsula dramatically easier, but the coastal railway is scenic enough that many people prefer it.
Where to stay, what to eat
Katsuura is the practical base. It is a tuna port — one of Japan's largest for longline-caught tuna — and the morning auction at the fish market can be watched from a gallery, usually from around 7am. Eat maguro for breakfast; everyone does. The town is also an onsen resort, with several large baths built into sea caves.
Inland, Yunomine Onsen near Hongu has been in continuous use for around 1,800 years and contains Tsuboyu, a tiny two-person wooden tub that is the only hot spring in the world inscribed as a World Heritage site. It is booked in thirty-minute slots on a first-come basis.
Practical notes
Mid-October daytime temperatures run around 20–23°C on the coast and noticeably cooler in the mountains; bring a light layer for evenings and something waterproof, since the Kii Peninsula is one of the wettest places in Japan year-round. Autumn colour arrives late here — the coastal areas do not really turn until well into November — so come for the festivals and the sea, not the maples.
Accommodation in Shingu is limited, and fills for the festival nights. Book before the end of September if you are targeting the 15th and 16th. Festival schedules are published by the individual shrines and can move; check locally on arrival.
