Best UX Design Agencies in Tokyo (2026)

Introduction

Tokyo has 11 UX design agencies worth a close look in 2026, ranging from Goodpatch, which in 2020 became the first design company listed on the Tokyo Stock Exchange, to usability consultancies whose history goes back to 1990. The list covers product design, UX research and digital experience work for clients.

Two themes run through the city’s 2025 and 2026 news. The first is AI: Goodpatch made Layermate, the developer of an AI design tool, a subsidiary in 2025, Monstarlab launched its MonstarX platform for enterprise prototyping that November, and Sun* released its Nova design system for AI-driven development in October 2026. The second is care for users at the edges of a product. Concent began offering full support for dark pattern prevention in September 2026, while U’eyes Design and Mitsue-Links both work to WCAG 2.2 in their accessibility services. Some global names are absent: frog’s and Designit’s published studio lists do not include Tokyo.

Every firm here showed an active Tokyo office on a page checked in 2026, and in-house design teams are left out. The list is unranked, since the right choice depends on your product, your users and how much of the build you want the same firm to handle.

The best UX design agencies in Tokyo

1. Goodpatch

Publicly listed (Tokyo Stock Exchange) · Shibuya · goodpatch.com

Goodpatch was founded in 2011 and moved from Akihabara to Shibuya in 2014. It works on UI and product design, vision prototyping and the design organisations behind them. Recent group changes include People and Design Inc. in 2024, then a Kansai office in Osaka and the addition of Layermate Inc. in 2025. It marked its 15th anniversary in 2026.

Featured work includes vision prototyping for Suzuki’s core systems, Kokuyo’s TEAMUS product, future-insight projects for Daikin and Kubota, and a Coop Deli app project. Several engagements centre on building a client’s own capability, such as the work with Toppan Digital on product management roles, so it suits companies that want in-house skills to remain after the project ends.

2. Concent

Japanese design company · Ebisu · concentinc.jp

Concent works alongside client companies on business development, corporate communication and creative production, from strategy through to execution. It has offices in Ebisu and also runs a design school site and a knowledge-sharing programme. In September 2026 it began offering full support for dark pattern prevention, covering organisational systems as well as screen fixes, based on work it has done since 2021.

Recent clients include the Digital Agency, Persol Holdings, Takenaka Teien Ryokka and Kokuyo, for which it produced a concept book on employee experience research. It also ran verification work on an AI femtech service for Fujiyama Bridge Lab. The range makes it a reasonable fit for public-sector and corporate projects where the service and the communication need to be designed together.

3. Monstarlab

Monstarlab group · Ebisu · monstar-lab.com

Monstarlab was founded in 2006 and has its Tokyo headquarters in Ebisu Prime Square Tower, with other Japanese locations in Osaka, Kobe, Sendai, Izumo and Matsue. It builds teams of engineers, designers and other specialists around each project. In December 2025 it adopted a new brand message around AI and digital partnership, and it launched MonstarX, its AI platform for enterprise prototyping, the month before.

Case studies include an app for Tokyo Dome City aimed at improving the customer experience, 3D and AR diagnostics for Kubota construction equipment, and a purchasing data dashboard for Kakujo Gyogyo Holdings. Its offer leans towards product development, so ask to meet the designers who would work on your project.

4. Takram

Design innovation firm · Jingumae · takram.com

Takram describes itself as a full-stack design partner, working across digital products, brand, industrial design, design engineering and business design. Its Tokyo office is in Jingumae, and it has further offices in London, New York and Shanghai. Its design engineering work appeared at Expo 2025 in “Dynamic Equilibrium of Life”.

Digital product projects include the H3 Flight Status Indication System for the public, the Serendie Design System, a Goldwin webstore revamp and work on geospatial rendering in Three.js. On the service side it lists Panasonic Vision UX and a guideline for service design process. It is a good fit for briefs where the interface, the physical product and the technology need to be considered by one team.

5. Accenture Song Japan

Part of Accenture · Akasaka · accenture.com

Accenture Song is one of Accenture’s practice areas, and Accenture’s Japan headquarters is in Akasaka Intercity AIR. Song’s design practice in Japan covers strategic design, visual design, UI and UX design, and design management, and it ran an in-person design internship in Tokyo for its 2026 intake. Accenture opened a Fjord studio in Tokyo some years ago, reported by Campaign Asia as the brand’s 33rd worldwide.

Designers work with consultants and engineers across strategy, AI, development and operations, which is the main reason to choose it over a specialist studio. Published Japanese client work is harder to find than at the smaller firms on this list, so ask for relevant case studies and the names of the design leads early in the process.

6. U’eyes Design

UX consultancy · Ebisu · ueyesdesign.co.jp

U’eyes Design traces its origins to 1990 and took its present name in 2005. It specialises in human-centred design and usability, with services spanning online research, usability evaluation, training and WAIV2, an automated accessibility evaluation tool aligned with JIS X 8341-3 and WCAG 2.2. Its Re-skilling course became an accredited course for the UX Certification (Applied) exam in 2025, and it spoke at CEATEC and Designship in 2026.

The client logos on its site include JR East, JTB, NTT, Canon, Toyota, Nissan, SoftBank and Panasonic. One published case covers continuous usability evaluation for the GUI of office multifunction printers, which reflects its strength in hardware and embedded interfaces as well as web services.

7. AQ

Design studio · Harajuku · aqworks.com

AQ is a design studio for digital products and services, with offices in Tokyo and Paris and a further base in Yatsugatake. Much of its work helps companies design for Japanese users: embedded design teams for the local market, UX research, UX audits with cultural context, and design discovery. It also organises and contributes to design events in Tokyo and abroad.

Clients include ASICS, for which it helped design and grow the MyASICS product over six years, Indeed, which it supported with research into Japanese job searching through home and office interviews, and Mercari, on accessibility for users with visual and motor impairments. GROKE, a Finnish marine technology company, worked with AQ on a first product with Japan as a key launch market. That record makes it a natural first call for overseas companies entering Japan.

8. Nijibox

Recruit Group · Kudanshita · nijibox.jp

Nijibox is part of the Recruit Group and works on service growth through UI and UX design, software development and data engineering. Its UX work covers support for growing existing services and launching new ones, and its UI work extends to design systems. Mynavi TECH+ ran a feature in March 2026 on its work building design systems for AI adoption.

Published cases include Air Closet, Chiba Bank and several Recruit services, among them design system overhauls, UX workshops and improvements to a large travel service. The firm also runs the free UI UX Camp! events and NIJIBOX College, a learning programme for organisations, which can be useful if training is part of the brief. Recruit features heavily in its case studies, so ask about experience outside the group.

9. Sun*

Publicly traded (securities code 4053) · Otemachi · sun-asterisk.com

Sun* calls itself a digital creative studio and has about 1,500 people across engineering, design and strategy consulting. Its Tokyo office is in the Otemachi Building. Teams combine technology, design and business staff for new business and product work, and in October 2026 it released Nova, a design system for AI-driven development, free of charge.

Named work includes KENDRIX for music rights management, the ourly internal communications service, the ALFALINK app for GLP and Monofull, and the Nissan Rent a Car app. It suits companies that want one partner from concept through to engineering and operations.

10. Loftwork

Privately held · Shibuya · loftwork.com

Loftwork was founded in February 2000 and has its main office in Dogenzaka, with 154 employees as of January 2026. It co-creates with companies and local governments across branding, service design, spatial design and open innovation, and it runs the FabCafe spaces. Hajime Matsui was appointed representative director and CEO in October 2026.

Its UX work includes research for Seven Bank into what keeps children using a financial education service. Other recent projects include a university campus platform and a programme around an exhibition with Honda R&D. It is better suited to exploratory briefs with several stakeholders than to pure interface production.

11. Mitsue-Links

Shareholder: Dentsu Soken · Nishi-Shinjuku · mitsue.co.jp

Mitsue-Links was founded in 1990 and has 407 employees. Its head office in Sumitomo Fudosan Shinjuku Grand Tower also houses a user test studio. It offers UX research in Japan (strategy, research, optimisation and usability testing) along with UI planning, web development and operations. Its accessibility expertise includes WCAG 2.2 compliance work.

It reports more than 500 clients a year, and named work includes an information accessibility portal for the Ministry of Internal Affairs and Communications. Its 2026 columns focus on AI search and accessibility as a foundation for AI agents. Large corporate websites that need long-term operation as well as UX input are its natural territory.

What to look for in a Tokyo UX design agency

Start with who your users are and how the research will reach them. Japanese-language interviews, home visits and usability testing sit at the centre of several firms here, including AQ, U’eyes Design and Mitsue-Links, and Mitsue-Links has its own test studio. If you are based overseas, ask how findings will be translated and reported, and whether your team can observe sessions directly.

Decide how much of the build belongs with the same firm. Sun*, Monstarlab and Nijibox combine design with engineering, while AQ concentrates on design and research, and can embed a team alongside yours. Goodpatch and Concent both put weight on the client’s organisation, which matters if you plan to keep the capability in-house.

Ask how AI is used in the work, and by whom. Several Tokyo firms have launched AI tools or platforms since 2025, and it is reasonable to ask which steps of research and design those tools touch, who reviews the output, and how your data is handled. The same conversation should cover accessibility and dark patterns, where both JIS X 8341-3 and WCAG 2.2 are useful reference points; your own legal team should make the final call on compliance.

Finally, look at how the agency handles research and review material. A UX project produces interview recordings, usability test videos, prototypes, screenshots and rounds of stakeholder comments, often in two languages. Agree early where this will live, who can see it, and how feedback is tracked to completion, because findings are only useful if the product team can find them later.

How Fabric helps UX design teams

Fabric gives a UX team one workspace for files, research and client feedback, with AI search across all of it. The setup for UI and UX agencies suits the way these firms work: one space per client, holding briefs, research, prototypes and call notes.

Research is usually the hardest material to reuse. Audio and video transcription makes uploaded interviews and usability sessions searchable, with clickable timestamps. Search works by meaning across documents, images, PDFs and those transcripts, and results jump to the relevant page or moment, so a researcher can find what participants said about onboarding without rewatching every session.

For synthesis and early design, the canvas is an infinite whiteboard that embeds Figma files alongside references and notes.

Feedback runs through shared links. Share a file or folder with a client as a commenter and they can respond without signing up, using threaded comments and annotations. They can leave timestamped comments on a test recording, draw on a video frame or a screenshot and attach a comment, or highlight text in a report. The team then marks each comment completed, so a round of feedback works like a checklist. There is more on comparing options in the best design feedback tools. When work is ready for a wider audience, any file or folder can be published as a web page. Published links are view-only.

On Team plans, self-writing docs maintain a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items. Files are protected with AES-256 encryption, Fabric is CASA Tier 2 certified, and data is not used to train AI models; whether that meets a given research consent or client requirement is for your own legal team to decide.

Team plans start from $125 a month. See plans for teams.

Frequently asked questions

What is the best UX design agency in Tokyo?

There is no single answer, as it depends on the product and the users. Goodpatch is a listed design company with a broad product portfolio, AQ is a strong starting point for overseas companies designing for Japan, and U’eyes Design has a usability record with origins in 1990.

Which Tokyo UX agencies work with overseas companies?

AQ focuses on this, offering embedded design teams, research and audits for the Japanese market to clients such as Indeed and GROKE. Mitsue-Links also offers UX research in Japan with plans tailored to the client’s target market.

Do frog and Designit have studios in Tokyo?

Neither lists one. As of November 2026, frog’s studio list and Designit’s studio list both leave out Tokyo, although both include other cities in the Asia-Pacific region.

Which firms can design and build a product?

Sun*, Monstarlab and Nijibox all combine design with software development. Sun* has about 1,500 people across engineering, design and strategy, while Nijibox adds data engineering and a large base of work within the Recruit Group.

How is a UX agency different from a design agency in Tokyo?

UX firms concentrate on research, product flows and interfaces, and they are usually measured on how a service performs for its users. If your brief is mainly identity, print or multidisciplinary studio work, see the best design agencies in Tokyo.
