Nikko’s main sightseeing route climbs from about 543 m at Tobu-Nikko Station to about 1,500 m at Yumoto Onsen, so the autumn colour starts at the top in September and works down to the shrines in November. Below: the Nikko Tourism Association’s timing by area, Tochigi’s 2026 Irohazaka traffic measures, and a one-day example route checked against the 2026 timetables.

If you have one day in October, I would go up the mountain first and leave the shrines for the afternoon. In mid-November, put the shrines first.

Timing by area: when each part of Nikko turns

The association says colour can be seen somewhere in Nikko from early September to late November. Its heights: Tobu-Nikko Station 543 m, the Toshogu area 634 m, Lake Chuzenji 1,269 m, Senjogahara about 1,400 m, Yumoto Onsen about 1,500 m.

The “expected peak” is the association’s forecast window; its photos show each spot at its best. Heights marked * are from the Geospatial Information Authority of Japan’s elevation service at the association’s map pins, rounded. Check the association’s autumn-leaves page the night before; the Japan Weather Association’s forecasts are on tenki.jp, and our Japan koyo tracker covers the whole country.

The spots, from the top of the valley down

Oku-Nikko, from Lake Chuzenji up to Lake Yunoko, sits at 1,300–1,500 m, says a Nikko City text; Senjogahara, Odashirogahara, the Yu River and Lake Yunoko are listed under the Ramsar Convention. Apart from the extra places at the end, every spot below is on or near the Tobu bus line from Nikko to Yumoto Onsen.

Yudaki Falls and Lake Yunoko

Lake Yunoko formed when an eruption of Mt Mitsudake dammed the Yu River. It is about 3 km round, with an hour-long shore path, and its mixed forest turns red, yellow and brown in early to mid-October.

Yudaki, at the south end, is about 70 m high and 110 m long: the lake water slides down the wall of the lava flow that made the lake, and a viewing deck stands at the foot. It is about 80 minutes by bus from Nikko Station plus five minutes on foot from Yutaki-iriguchi. By 14 October 2026 the association had the lake and Yudaki at the start of their peak.

Senjogahara

Senjogahara is a 400-hectare marsh that was once a lake; its name, “battlefield plain”, comes from a myth that the gods of Mt Nantai and Mt Akagi fought here over Lake Chuzenji. The association recommends late September to early October for the grass, and lists the trees for mid to late October; its congestion feature also points to the morning mist around sunrise, at about 5:30. The viewpoint is at the Sanbonmatsu bus stop, about 70 minutes from Nikko Station; for the walk, get off earlier at Akanuma.

Ryuzu Falls

Ryuzu, the “dragon’s head”, runs for about 210 m down a stair of lava from Mt Nantai, about 10 m wide. A large rock splits it near the bottom: the head, with the two streams as whiskers. Its colour, from late September, is said to be the earliest in the city, with maples and Japanese linden. It is about 65 minutes by bus from Nikko Station, then two minutes on foot from the Ryuzu-no-taki stop.

Lake Chuzenji

Lake Chuzenji (1,269 m) is about 25 km round and up to 163 m deep, and took shape about 20,000 years ago when lava from Mt Nantai dammed the valley. From the Meiji era to the early Showa years it was a summer retreat for foreign visitors; in the colour season the cruise boats run an autumn course.

On the south shore, two former embassy summer villas are now parks. Tochigi Prefecture (page updated 1 September 2026) lists the British and Italian Embassy Villa Memorial Parks as open to 30 November, 9:00–17:00 until 10 November and 9:00–16:00 after, at ¥300 for adults each or ¥450 for both. A seasonal Tobu bus from Chuzenji Onsen to Hangetsuyama stops near the parks: 1 October to 8 November 2026 per Tobu (the prefecture lists 12 November without a service year).

Kegon Falls

Kegon is where Lake Chuzenji pours over a cliff about 97 m high, counted among Japan’s three great waterfalls, about five minutes on foot from the Chuzenji Onsen bus stop. There is a free viewing deck at ground level with a steep ramp (the association says wheelchair users need a helper), and an elevator down to a deck near the basin: 8:00–17:00 from 1 March to 30 November, last entry 20 minutes before closing, ¥600 return for adults and junior high pupils, ¥400 for primary pupils. It can stop in bad weather.

Irohazaka and Akechidaira

The Irohazaka is two one-way roads between town and Lake Chuzenji: the First goes down, the Second goes up. Between them they have 48 sharp bends, each signed with a letter of the old iroha syllabary, and they climb about 440 m. The association says it is known as the most beautiful place for autumn colour in Nikko.

The classic view of the hairpins is from the Akechidaira deck at 1,373 m, three minutes by ropeway from near the top of the Second Irohazaka. The ropeway closed for renovation after 15 January 2026 and plans to reopen in September 2027, so in autumn 2026 there is no ride up to that view.

Shinkyo bridge and Toshogu

The red-lacquered Shinkyo bridge belongs to Futarasan Shrine and marks the way into the shrine area. Legend says two snakes sent by a deity, with sedge growing on their backs, became a bridge for the monk Shodo Shonin here. It took its red form in the rebuilding of 1636, was washed away in 1902 and rebuilt in 1904. Crossing costs ¥300 for adults: 8:30–16:30 April to October, 9:30–15:30 from November.

Nikko Toshogu enshrines Tokugawa Ieyasu, the first Tokugawa shogun. Most of its buildings were rebuilt in the great rebuilding of 1636 under the third shogun, Iemitsu; the grounds hold 55 buildings, eight of them National Treasures and 34 Important Cultural Properties. It is open 9:00–17:00 until 31 October and 9:00–16:00 from 1 November, last entry 30 minutes before closing; adults pay ¥1,600. See our Toshogu guide.

Kanmangafuchi

Upriver from the shrines, Kanmangafuchi is a small gorge on the Daiya River cut through lava from Mt Nantai. About 70 stone Jizo statues stand on the south bank, nicknamed the “ghost Jizo” because the count is said to change every time. The association warns that leeches are often reported on the paths here from June to October, especially in rain or the day after.

Other places the association tracks

Irohazaka traffic in autumn

The association says the climb normally takes about 20 minutes; in a jam two to three hours is common, and up to six hours has happened during holiday runs. Its 2026 feature names colour-season weekends, especially mid-October to early November, as the worst (peak colour brings weekday jams too) and 9:00–15:00 as the bad window, sometimes to 17:00 on weekends; at 14:00–15:00 it can take over three hours.

The association’s congestion calendar (September 2026 edition, built from past years) marks these days red, its top band: more than 120 minutes from the station to Lake Chuzenji, or more than 60 minutes to the shrine area.

Every other day from 19 October to 19 November is in the next band: 80–120 minutes from the station to Lake Chuzenji, or 30–60 minutes to the shrine area. Even on a Tuesday, the bus up can take far longer than the timetable.

What Tochigi, Nikko City and Tobu are doing in 2026

The off-peak advice lines up. Tochigi: a Tuesday to Thursday, before about 8:00 or after 15:00, by public transport. The association: before 7:00 on weekends and holidays, after 15:00 on weekdays. The bus sits in the same queue, but you skip the parking hunt.

Getting there from Tokyo, and up the valley

Trains to Nikko

Tobu gives about 1 hour 50 minutes from Asakusa to Tobu-Nikko by limited express, and 2 hours from JR Shinjuku direct. Tobu limited-express tickets, including Spacia X, are sold online (with a site for overseas visitors), at Tobu stations and by travel agents; buy both legs ahead. From Asakusa the fare is ¥1,400 plus a standard-seat limited-express charge of ¥1,940 on normal days or ¥2,140 on Tobu’s busy days; in October and November 2026 those are the weekends and most public holidays on Tobu’s calendar (not 3 November).

Tobu’s NIKKO PASS all area costs ¥8,000 for adults for four days, for foreign visitors (Japanese nationals travelling with them can also buy it). It includes one return between Asakusa and Shimo-Imaichi, Tobu trains between Shimo-Imaichi and Tobu-Nikko, all Tobu buses in Nikko and the Lake Chuzenji cruise boats; limited-express charges are extra.

Buses up the valley

Tobu buses for Chuzenji Onsen and Yumoto Onsen leave JR Nikko Station and, three minutes later, Tobu-Nikko Station. Times are from the timetable valid 1 April to 30 November 2026 and assume no traffic.

The first bus leaves JR Nikko at 6:06 and is timed into Chuzenji Onsen at 6:54 and Akanuma at 7:13. From 9:05 to 16:30, 23 timetabled buses from Tobu-Nikko reach Chuzenji (gaps up to 40 minutes); the association says extra buses may run at peak. The last bus down leaves Yumoto at 19:30, timed into Tobu-Nikko at 20:38.

Tobu Bus sells two-day free passes: Chuzenji Onsen ¥2,300 and Yumoto Onsen ¥3,500 for adults. A plain return to Yumoto is ¥3,900.

If you drive, follow the association’s timing: on weekends be on the Irohazaka before 7:00, on weekdays after 15:00 (I would avoid red days). Our Irohazaka winter driving guide covers the bends and the road itself.

A one-day route from Tokyo in late October

This is an example for a lighter-traffic day, not a guarantee. The arrival range assumes you catch the 9:45 on a day that is not red on the association’s calendar, where the station to Lake Chuzenji takes 80–120 minutes. The calendar gives no figure for the way down, and Tobu’s timetable warns of big delays, so expect the bus down to run late too.

If the 9:45 is full: the next buses leave at 9:55 (an express, from stop 2E) and 10:05, timetabled 10–20 minutes later; real delays can be longer. Drop the lakeshore walk, keep Kegon Falls, eat quickly and head for stop 26B early. If the queues put the 14:10 bus down out of reach, cut Kegon too and take the next bus down; if you will not have time to get off at Tobu-Nikko and board the 17:44, use the rail backup below.

If the bus down is late

The later buses leave Ryuzu-no-taki at 14:41 and Chuzenji Onsen 26B at 15:00, due at Shinkyo at 15:29 on the timetable and later in traffic: see the bridge from the road and skip Toshogu.

The 16:20 in the table is only my target: buses leaving Shinkyo at 16:57 and 17:04 are still timetabled into Tobu-Nikko before 17:44. Switch to JR if you will not have time to get off at Tobu-Nikko and board the 17:44. On an ordinary bus, stay aboard past Tobu-Nikko to JR Nikko, 2–4 minutes later on the timetable. On an EX express, which skips Shinkyo and JR Nikko, get off at Tobu-Nikko and make your way to JR Nikko. At the shrines? Take an ordinary bus straight to JR Nikko. Check Tobu’s ticket-change rules when you buy.

The JR backup (JR East, October 2026): Nikko Line trains from JR Nikko at 18:19, 19:19 and 20:04 reach Utsunomiya at 19:02, 20:02 and 20:50, and Tokyo-bound shinkansen leave Utsunomiya at 19:22, 20:23 and 21:10. The day’s last Tokyo-bound shinkansen from Utsunomiya is scheduled at 22:54; the 21:52 from JR Nikko (Utsunomiya 22:32) is the last train to reach it. JR fares are not covered by Tobu tickets or the NIKKO PASS.

Other versions of the day

Where to stay for the colour

Nikko town suits the shrines and an early train home, but starts every day below the Irohazaka. Chuzenji Onsen puts Kegon Falls and the lakeshore on your doorstep. Yumoto Onsen, at the end of the bus line, is closest to Yudaki and Senjogahara. Kamenoi Hotel Oku-Nikko Yumoto stands by Lake Yunoko; our Kamenoi Hotel review covers the rooms and the sulphur baths.

Weather and what to wear

These are the Japan Meteorological Agency’s 1991–2020 averages for its Oku-Nikko station:

An October low near 6°C means a warm mid-layer and a windproof jacket; a November low near freezing means a coat, gloves and a hat. October is wetter, so pack a rain shell and shoes with grip. Our November packing guide goes through the layers.

Who this trip suits

This plan suits travellers who can go midweek and start early; for this late-October lake route, consider a night at the lake when the calendar marks the Irohazaka red.
