Tokyo burned down in 1923 and again in 1945, which means almost nothing in the city is old. What looks like a contradiction, a 7th-century temple two stops from a glass tower shaped like a stack of bento boxes, is really the same thing: a city that rebuilds constantly and treats every new building as a chance to try something.
Tokyo architecture is best seen on foot in three or four specific districts. Omotesando has the highest concentration of flagship buildings by famous architects anywhere in the world, Ginza has the luxury facades, Roppongi has the museums, and Asakusa has what survived. Most of it is free to look at from the street.

Three things. Density, which produces very narrow buildings on very small plots. Impermanence, since the average Tokyo building is replaced after around 30 years, far sooner than in Europe. And a willingness to hand a small commercial site to an ambitious architect and see what happens.
That last one is why a cake shop, a jewelry store and a dental clinic can all be significant works of architecture here. The budget goes into the envelope rather than the interior, because the building is the advertisement.
We'll build a costed, pre-planned Japan itinerary you can customise to your taste.
A 1.1 km boulevard of zelkova trees between Harajuku Station and Aoyama, Omotesando has more buildings by Pritzker Prize winners per meter than anywhere else. The walk takes 30 minutes and costs nothing.
Tod's Omotesando by Toyo Ito wraps the building in a concrete lattice modeled on the silhouette of the zelkova trees outside, with the glass poured into the gaps. The structure and the decoration are the same thing.

Prada Aoyama by Herzog and de Meuron is a five-sided glass crystal of 840 rhomboid panels, some flat, some convex, some concave, so the street outside warps as you walk past. The building's own history page covers the engineering.
Sunny Hills by Kengo Kuma, one street back in Aoyama, is a pineapple cake shop built as a basket of 5,000 interlocking cedar sticks using a traditional joinery technique called jigoku-gumi, hell joint, with no nails or glue. Buy a cake, look at the ceiling. The shop's site lists opening hours.
Also on the street: Dior Omotesando by SANAA, Omotesando Hills by Tadao Ando, which spirals downward at the same gradient as the slope outside, and the Gyre building with its twisted floor plates.

Tadao Ando is the architect most visitors want to see, and Tokyo has two accessible works.
21_21 Design Sight in Tokyo Midtown, Roppongi, opened in 2007 with Issey Miyake. Most of the building is underground, and what shows above ground is two long steel roof plates folded like a single sheet of fabric, a reference to Miyake's clothing. Admission depends on the current exhibition, and it closes on Tuesdays.
Omotesando Hills, completed in 2006, replaced a 1927 apartment block and reproduces one section of it at the western end. Inside, a continuous ramp spirals down six levels at the exact slope of the hill outside. Entry is free.
Ando's signature is board-formed concrete, poured against cedar planks so the grain and the bolt holes stay visible. Once you have seen it you will recognize it anywhere.

The National Art Center by Kisho Kurokawa has a 160 meter glass facade that undulates in and out, with two inverted concrete cones inside holding a cafe and a restaurant at their tops. It holds no permanent collection, only touring exhibitions, and the building is the reason to go. Entry to the building and its cafes is free, with exhibitions charged separately. The center's site lists what is on.

Roppongi Hills and Tokyo Midtown add the Mori Art Museum, the Suntory Museum of Art and a cluster of public sculpture, all within a 15-minute walk of each other.

Ginza is where luxury brands spend money on skins. Louis Vuitton's Matsuya Ginza facade, redesigned by Jun Aoki, uses layered glass to suggest water in motion, and it changes completely after dark. Mikimoto Ginza 2 by Toyo Ito is a pink steel tube punched with irregular windows and no visible columns.
De Beers Ginza curves like a ribbon, Nicolas G. Hayek Center has trees growing up through a glass shaft, and Ginza Six is the big recent one with a Yayoi Kusama installation in the atrium.
Come at dusk when the facades light up. It is a 20-minute walk from Ginza Station to Ginza Six with a dozen worthwhile buildings on the way.

Kisho Kurokawa's Nakagin Capsule Tower, completed in 1972, was the built masterpiece of the Metabolist movement: 140 prefabricated capsules, each 2.3 by 3.8 meters with a single round window, bolted onto two concrete cores and theoretically replaceable every 25 years.
None were ever replaced. The building deteriorated, asbestos was found, and it was dismantled in 2022.
Twenty-three capsules were saved, cleared of hazardous material and restored. Several are now in museum collections, including the Museum of Modern Art in New York and SFMOMA, and others tour as exhibits in Japan. Check current listings before traveling for one, since they move.

Tokyo Tower, completed in 1958, is 333 meters of hand-riveted steel designed by Tachu Naito, nine meters taller than the Eiffel Tower and built with about half the steel. It is painted international orange and white because aviation law required it. The Main Deck is ¥1,200 at the counter, and a a tower ticket bundled with a subway pass covers the day's transport too.

The Skytree tower, finished in 2012 at 634 meters, uses a central concrete column that moves independently of the steel frame, a damping system borrowed from the five-story pagoda, which is why 1,300 years of pagodas have survived earthquakes. Its cross-section morphs from a triangle at the base to a circle at the top. Panoramic view tickets skip the ticket queue.

Iidabashi Station on the Oedo Line, by Makoto Sei Watanabe, uses a green web of steel tubes generated by algorithm, growing out of the entrance like a plant. It costs nothing to walk through with a train ticket.
Tokyo International Forum by Rafael Viñoly is a 60-meter glass hall shaped like the hull of a ship, with ribs of white steel and walkways crossing the void. It is open to the public, free, and almost empty on weekday afternoons.

Sumida Hokusai Museum by Kazuyo Sejima is a mirror-clad block in a residential district, sliced with angled cuts that reflect the neighborhood back at itself. Admission to the permanent collection is modest and the building is the point.

St. Mary's Cathedral in Bunkyo, by Kenzo Tange in 1964, is a stainless-steel hyperbolic paraboloid in the shape of a cross when seen from above, with light entering through the joints between the surfaces. The cathedral's history explains how it replaced a Gothic church lost in the war.
Harajuku Church by Ciel Rouge Création has a curved interior designed around a nine-second reverberation time, so the acoustics shape the geometry. The project documentation shows the sections, and it sits a short walk from Harajuku Station.
Senso-ji in Asakusa was founded in 645, though the current buildings are postwar concrete reconstructions faithful to the originals. The temple's long history is the reason to read up before you go, and the temple grounds are free and open around the clock.

Yasukuni Shrine uses a plain Shinto style with the largest bronze torii in Japan, and the shrine grounds hold rows of cherry trees that Tokyo's official blossom forecast is measured against. Sengaku-ji, where the 47 ronin are buried, is small, quiet and free, and the temple in Takanawa is a ten-minute walk from Shinagawa.
Traditional Japanese building logic, wood, post and beam, deep eaves and a garden framed as a view, carries over into the modern work. It is the same instinct you see in Japan's quieter garden design.
Walk it in districts rather than chasing individual buildings across the wider city. Three half-days covers the essentials.
Omotesando and Aoyama: Tod's, Prada, Sunny Hills, Dior, Omotesando Hills. Two hours, free
Ginza: the luxury facades from Ginza Station to Ginza Six, best after dark. 90 minutes, free
Roppongi: National Art Center, 21_21 Design Sight, Mori Art Museum. Half a day, ¥1,000 to ¥2,500 in admissions
Add Tokyo International Forum near Tokyo Station and Iidabashi Station, both free and both five minutes off other routes.
Most of Tokyo's architecture is free, because the significant part is the outside. Budget only for what you want to enter.
Street walking: free
National Art Center building and cafes: free, exhibitions ¥1,000 to ¥1,800
21_21 Design Sight: varies by exhibition, usually ¥1,200 or so
Tokyo Tower Main Deck: ¥1,200 at the counter
Guided architecture tours: ¥5,000 to ¥15,000 for a half day
Bring comfortable shoes rather than money. A slower Tokyo route leaves enough time in each neighborhood to actually look up, which is the whole trick here.
If you have any interest in buildings, it is the best walking city in the world for it, and most of it is free.
If you do not, you will still pass a dozen of these on the way to somewhere else. Omotesando is on the route between Harajuku and Shibuya, Ginza is a shopping street, and the Oedo Line is how you get around. The architecture is not a detour here. It is the city.
