Mid Oct
The lake and the top of the road
Lake Chuzenji and the upper Irohazaka turn first, and they turn hard. This is the fortnight the photographs come from, and the road is already busy at weekends.
Autumn
The colour arrives at the top of the mountain first and works downward over about a month, which means there is no single right week — there is a right week for the lake and a different one for the shrine. Getting that wrong is the commonest autumn mistake in this part of Japan.

Quick answer
Autumn colour reaches Lake Chuzenji and the Irohazaka road first, usually in mid to late October, and the shrine district below around early to mid November. It is the busiest fortnight of the Nikko year: the mountain road queues badly and tours run late. Book weeks ahead and treat the schedule as approximate.
Week by week
Altitude decides everything. The lake is at 1,269 metres and the shrine is at about 600.
Mid Oct
Lake Chuzenji and the upper Irohazaka turn first, and they turn hard. This is the fortnight the photographs come from, and the road is already busy at weekends.
Late Oct
The colour works down the forty-eight bends. Peak traffic, peak photography and the best single view of the year from the top of the ascending route.
Early Nov
The maples around Toshogu and along the cedar avenue turn. The lake is going over by now, so this is the week to come if the shrine is the priority.
Mid Nov
Colour on the river and around the Shinkyo bridge, thinning crowds, and cheaper accommodation. A good compromise week.
Late Nov
The mountains are bare and the first snow can be on the way. Toshogu is still Toshogu, and the lake tours start to get thin.
The trade
The best fortnight of the year, and the worst traffic. Come midweek.
Yes, and you should know exactly what you are buying.
What you get is genuinely the best two weeks of the Japanese year in one of the best places for it: a mountain road switchbacking through maples, a lake ringed with colour at one thousand two hundred metres, and a shrine complex in gold leaf under red trees. It is not oversold.
What you also get is the traffic. The Irohazaka road is the destination for a large share of the Tokyo region on an autumn weekend, and a forty-minute climb can take well over an hour. Coach tours run late in that fortnight as a matter of routine. If your evening in Tokyo has something booked at seven, move it.
Two things help. Come on a weekday rather than a weekend, which halves the road problem. And decide in advance whether you are coming for the lake or the shrine, because they peak two to three weeks apart and trying to hit both is how people end up seeing neither at its best.
The mountain road is the thing autumn is really about, and not every tour goes up it.

Twelve tours, cheapest first. The lake column is the autumn column: the tours that reach Chuzenji are the ones that drive the Irohazaka.

Common questions
At Lake Chuzenji and on the upper Irohazaka road from about mid to late October, and in the shrine district below from early to mid November. Altitude sets the timing, and the difference between the two is two to three weeks.
Very, in late October and early November. The Irohazaka road is a major weekend outing from the Tokyo region and it queues badly. Weekdays are substantially better.
Two to three weeks ahead for the peak fortnight. The tours that include the lake sell out first because that is where the colour is.
Routinely, because of the traffic on the mountain road. Assume a later return to Tokyo than the listing states and do not book anything tight for that evening.
The lake, if you can time it — the road up is the reason people come. But it turns two to three weeks earlier, so the answer depends entirely on the week you have.
