Japanese Localization Services in India: Software, Websites, Apps and Games

Entering the Japanese market takes more than translated words. Your interface, your help files, your payment options and even your date format all need to feel natural to a Japanese user. Honyaku Services provides Japanese localization (L10n) for software, websites, mobile apps and games, from our base in Bangalore, with native Japanese translators who also understand IT.

We work only with Japanese and English, and we handle IT, software, app and marketing content for development teams, IT companies and businesses that are entering Japan or releasing products from Japan.

Japanese software and app localization

Localization problems usually show up as inconsistency: the same feature called three different things in the interface, the help file and the manual. When we review translated content, we check and correct terminology across:

Graphical user interface (GUI): buttons, menus and navigation labels.
Dialogue boxes and error messages: clear, natural in-app text in context.
Help files and tutorials: read-me files, FAQs and onboarding content.
User manuals and guides: technical and non-technical instructions adapted for Japanese users.
Release notes and installation guides: precise wording for updates and setup.

We also translate the documentation behind the product: technical specifications, developer guides, architecture documents, test cases, requirement and functional specifications, project reports and agile workflow documents. For more on technical documents, see our Japanese technical translation page. For software development meetings and client calls, see our Japanese interpretation services.

Technical details we check

Good localization is as much about engineering as about language. On a Japanese release we look at:

Character encoding: UTF-8, so Japanese text does not turn into garbled characters.
Fonts: Japanese fonts that are legible and look right.
Text direction: Japanese in software is normally set horizontally, left to right. Vertical writing is used in some publishing and design contexts, so we check that your layout supports the direction your product needs.
Formats: Japanese date and time (YYYY/MM/DD), yen currency, metric units, number formatting and Japanese address formats.
Keyboard shortcuts: adapted to the preferences of Japanese users.
Interface layout: adjusted for Japanese text length and screen sizes.

Japanese website localization

A Japanese website needs more than translated pages. We help you with:

Content: all text, images and videos translated and adapted.
Search visibility: content optimised for Japanese search. A .jp domain is worth considering for local targeting.
Payments: options Japanese customers expect, such as credit cards and convenience store payment.
Customer support: Japanese-language support channels.
Design and culture: layout, tone and imagery that suit Japanese preferences, and a check to avoid insensitive content.
Mobile and accessibility: a site that works well on phones, where usage in Japan is high, and is accessible to people with disabilities.

Japanese to English game localization

We localize Japanese video games and apps for English-speaking players, including RPGs, action games, simulation titles, mobile apps and VR experiences. Dialogue, menus, tutorials, in-game text, storylines, help files, manuals and release notes are translated naturally, so the tone and gameplay experience survive the move. We also provide voice-over scripts, UI localization and subtitle translation, and we keep cultural references working for the new audience.

For every game project we keep a glossary database, so the same character name, item and gaming term is used consistently from start to finish.

Japanese subtitle translation

We translate subtitles for films, documentaries, marketing videos, e-learning modules, software tutorials and corporate presentations. Our linguists transcribe, translate and synchronise by hand, rather than relying on automated subtitling, so the timing, readability and technical terms hold up. If you only need a transcript or text from a recording, see our Japanese transcription page.

Quality assurance and testing

QA testing: we look for localization problems, such as truncated text, wrong terms and layout breaks, and fix them.
User testing: feedback from Japanese users shows what real-world readers find unclear.
Continuous localization: we keep your content up to date as your product and the language evolve.
Cultural checks: a review for anything inappropriate in text or imagery.

Why companies choose us

Native translators with IT knowledge. Our translators combine native Japanese with experience in IT, engineering and business content, so they understand what an interface string actually does.

Human judgement. Machine translation tools are fine for a rough idea, but they cannot judge tone, context and culture. For content your customers will read, a person needs to be responsible for every word.

Fair pricing. We offer cost-effective rates, and pricing for very large localization projects is negotiable.

Confidentiality. Unreleased software and business documents are sensitive. We can sign an NDA before you send anything.

Reliable delivery. We handle both small tasks and large projects, and we are used to tight deadlines.

Industries we serve

IT and software, electronics and automotive, mechanical and industrial engineering, biotechnology and medical devices, semiconductors and machinery, finance and M&A, marketing and business presentations, and video games, apps and subtitling.
