Nagoya in October: Weather, Autumn Food and Castle Days

In October the smell of grilled eel and sweet soy drifts out of the hitsumabushi restaurants, chestnut sweets fill the shop windows, and the copper-green roofs of Nagoya Castle stand clear against a softer sky. The heat of summer has let go, and the city, a big working hub with a food culture all its own, is pleasant to cross on foot. This is a month for castle grounds, shrine paths and long lunches of local specialties.

What is the weather like in Nagoya in October?

October in Nagoya is mild and comfortable, with warm days, cooler nights and noticeably less rain than in September.

Month	Average high (°F)	Average low (°F)	Precipitation (in)	Days with 1 mm or more of precipitation	Hours of sunshine	Daylight on the 15th
September	84.4	69.8	9.12	10.5	160	12 h 27 min
October	73.9	58.6	6.48	9.0	169	11 h 22 min
November	63.1	47.5	3.11	6.1	167	10 h 21 min

Afternoons reach the mid-70s, which suits a day of sightseeing in a short-sleeved shirt or a thin long-sleeved one. Once the sun is down, the lows in the upper 50s call for a light jacket or a cardigan, especially if dinner is at a table outside or you are heading back on foot.

Rain still falls on about nine days of the month, so a compact umbrella earns its place in the daypack. Shoes that handle damp pavement are more useful than a heavy raincoat.

Sunshine is generous, and daylight is shrinking: the evenings close in earlier than they did a month ago. That is worth bearing in mind when you plan a late visit to a garden or a park, because the light fades while you are still wandering.

What to do in Nagoya in October

October in Nagoya revolves around autumn on a plate and a long stroll between its landmarks. Nagoya is the capital of Aichi Prefecture, on the Pacific coast in central Honshu, and it is Japan’s fourth-largest city. It is known for Atsuta Shrine, Nagoya Castle, the Higashiyama Zoo and Botanical Gardens and the Port of Nagoya Public Aquarium, all of which suit the temperate weather of this month.

Maple leaves around Nagoya have not turned yet, since their color change at the city usually comes near the end of November. October is therefore about green gardens, ripening chestnuts and persimmons, and the first hints of autumn rather than a leaf-peeping trip.

Nagoya Castle and its autumn festival

The castle is the city’s anchor, with its golden shachi, the mythical fish with a tiger’s head, crowning the main keep. You can walk the grounds, look up at the stone walls and the green roofs, and step into the Honmaru Palace, where painted screens and wooden corridors show how a lord’s household was arranged.

The castle holds an Autumn Festival, and during it admission to the Honmaru Palace runs until one hour before the gates close. Even with a festival on, the grounds are broad enough to absorb a good visitors, and the stone walls and moat edges make good places to slow down.

Atsuta Shrine and the old Nagoya

Atsuta Shrine is a forest of camphor trees around a Shinto sanctuary, and the gravel paths lead from the busy city into a hush of wood and shade. It is a place to walk without hurry, to watch visitors bow at the main hall, and to read the votive plaques and lanterns.

Near the shrine grounds, small stalls and restaurants serve a local sweet or a bowl of noodles. In October, with the heat of summer gone, the paths feel gentle in the shade and the stop for tea or kishimen, flat wheat noodles in a light broth, comes naturally.

Zoo, gardens, aquarium and the NAGOYA Sightseeing Pass

Higashiyama Zoo and Botanical Gardens combine animals and planted gardens in one large park, and the Port of Nagoya Public Aquarium gives a good indoor option when the sky turns gray. Chubu Electric Power MIRAI TOWER rises in the city center and gives a view over the streets.

The NAGOYA Sightseeing Pass is a great-value way to enjoy several major attractions, including Nagoya Castle, Chubu Electric Power MIRAI TOWER, the Port of Nagoya Public Aquarium, and Higashiyama Zoo and Botanical Gardens. It suits a visitor who plans to see all of these in one trip.

Nagoya meshi: eating the city in autumn

Nagoya has a cuisine of its own, called Nagoya meshi, and October’s cooler air makes its rich flavors easy to enjoy. Miso katsu is a fried pork cutlet under a dark, sweet red-miso sauce. Hitsumabushi is grilled eel on rice, eaten in three stages: plain, then with condiments, then as a tea-broth soup.

Tebasaki, crisp chicken wings with pepper and sesame, goes with a cold beer at an izakaya, the casual pub where locals gather after work. Ankake spaghetti, thick noodles in a peppery sauce, is a stranger local taste. In the pastry shops this season brings chestnuts, in cakes, in sweet pastes and in mochi.

Beyond the plates, the shopping arcades around Osu and the department stores and basement food halls of the Sakae district fill the rainy hours with browsing. October evenings suit a slow walk between restaurants, with a lantern-lit alley or two to wander.

A two-day itinerary for Nagoya in October

Day 1 starts at Nagoya Castle, where the grounds and the Honmaru Palace take the morning. The light stays long enough for a slow visit, and the cooler air means you can circle the walls without feeling the sun. Lunch is miso katsu or a bowl of kishimen at a casual restaurant near the castle.

In the afternoon, move into the city center for the Osu shopping arcades, with their secondhand shops, snack stalls and small temples, and then on to Sakae and Chubu Electric Power MIRAI TOWER. With daylight lasting a little over eleven hours, the tower is a good way to see the city as the sky changes. Dinner is hitsumabushi, grilled eel on rice, at a specialist restaurant.

Day 2 begins at Atsuta Shrine, among the camphor trees, with time for the main hall, the lanterns and a snack. Then it is Higashiyama Zoo and Botanical Gardens for the afternoon, where the autumn greens and early seasonal flowers fill the paths. Finish with tebasaki and beer at an izakaya, since chicken wings are the local way to end a day.

If the weather turns on either day, the Port of Nagoya Public Aquarium is the indoor swap for the zoo, and the covered Osu arcades and Sakae department stores can absorb the castle hours that are left.

Is Nagoya busy in October?

Nagoya is a big metropolitan city, so the streets are never empty, but October brings a steady autumn rhythm rather than a single rush. The city sits at the center of a metropolitan area of about ten million people, and its pace is set mainly by locals going to work, to school and to lunch.

What changes in October is the calendar of outings. The castle’s Autumn Festival adds a seasonal reason to visit, and the milder weather brings people into the parks, the zoo and the shrine grounds. Elsewhere in the region, the Autumn Takayama Festival is held on October 9 and 10 in Takayama, which gives the month a festival feel across central Japan.

On the streets and in restaurants, the mood is of a working city settling into a new season. Lunchtime in the Nagoya meshi restaurants is the moment when the city shows itself most clearly, with office workers and visitors sharing the same counters. Between meals, the sights are large enough to give everyone space.

What to pack for Nagoya in October

October asks for layers and a little rain protection, plus shoes for a lot of walking on pavement and gravel.

A light jacket or cardigan, for the nights when the lows drop into the upper 50s.
Short and long sleeves, since afternoons in the mid-70s are warm for walking.
A compact umbrella, because rain falls on about nine days of the month.
Comfortable walking shoes for the castle grounds, the shrine paths and the zoo.
Shoes that slip on and off easily, for palace interiors and restaurants with tatami floors.
A small daypack for a camera, a water bottle and the umbrella.

Good to know before you go

Rain in October is lighter than in September, but it still falls on several days, so keep an indoor option in mind for each day. Nagoya is a large city with many things to see under a roof, from the aquarium to the department stores.

The Japan Meteorological Agency launched its Emergency Warning System on 30 August 2013 to alert people to the significant likelihood of catastrophes from natural phenomena of extraordinary magnitude. The Japan National Tourism Organization also provides a Japan Safe Travel Information page with safety tips and government information for travelers.

Nagoya in October vs September and November

Going four weeks earlier means September, when the afternoons are hot and humid and more rain falls, with the wettest of the three months in the table. Sightseeing in the open air asks for more water and more breaks, and the days are longer by about an hour. The city’s food is the same, but a bowl of hitsumabushi is a heavier meal in the warmth.

Going four weeks later means November, when the air turns properly cool and rain becomes less frequent. Maple leaves at Nagoya usually turn around the end of that month, so garden visits gain a color that October lacks. Daylight is shorter, so the sights close around you earlier in the evening.

Travelers who dislike heat and want long walks should choose October, which sits comfortably between the two. Those who want to see red maples should shift to the end of November, and those who want the longest days and don’t mind the warmth can stay with September.

Is October a good time to visit Nagoya?

Yes, October is a good time to visit Nagoya, especially for travelers who want to walk a lot, eat well and keep their sightseeing open-air. The temperature suits long days around the castle, the shrine and the zoo, and the rain is lighter than in the month before.

Food lovers will find the month particularly rewarding, since the heavy, savory dishes of Nagoya meshi taste right in cooler air and chestnut sweets appear in the shops. Those who come only for autumn leaves should wait for late November, and anyone who wants a beach trip or hot-weather swimming will find the season has moved on.

On arrival, start with Nagoya Castle, whose grounds give you a sense of the city’s scale and its history. What sets October apart in Nagoya is the combination of golden roof tiles, a plate of miso katsu and an Autumn Festival at the castle, all in air mild enough to enjoy them outside.
