Japanese Translation Trends

As the world’s 3rd largest economy heavily dependent on commercial import/export, Japan requires professional English-Japanese translation services more than any other country in the world relative to its national GDP to support international trade. Like businesses in Germany, Japanese companies take great pride in building global brands that manufacture high-quality products around the world, creating a huge demand for new translation solutions that deliver improved linguistic quality, speed, and scalability. The digital transformation creates ample opportunities for a new range of Japanese media translation services.

Artificial Intelligence

Artificial intelligence (AI) is fundamentally changing the way the localization industry does its work, from machine translation and real-time file analysis to automated linguistic resource management and workflow automation. Unlike previous misconceptions that AI only has significance in machine translation (MT), in reality AI impacts every step of the Japanese translation process, from file preparation and translation reuse to translator assignment and automated linguistic validation. Stepes is a leader in AI powered Japanese translation solutions that significantly improve our clients’ localization ROI. To learn more about Stepes AI-powered translations, please click here.

Japanese Video Translation

80% of all internet content today is consumed in the form of video and Japan is no exception.

There is a huge demand for video translation services between English and Japanese that require fully streamlined workflows, such as automatic transcription with time codes, subtitling with SRT, and voice over. Stepes is the first localizer within the language industry to introduce on-demand video translation solutions in Japanese and 100 other languages.

Machine Translation Post Editing (MTPE)

Let’s face it, professional Japanese translation is expensive. Prior to when CAT tools were first developed, companies used to charge $0.48 a word for English-Japanese translations. Machine translations have come a long way. However, its quality is still insufficient to be customer facing. The good news is machine translation post-editing services or MTEP promises a great solution. This new translation process uses MT to pre-translate the text into Japanese. Next, professional Japanese translators are brought in to edit the results so the final output has the highest linguistic quality. To learn more about Stepes MTPE solutions, please click here.

The Japanese Translation Market

The Japanese Translation Market

The volume of English to Japanese translation has consistently ranked one of the highest among all languages within the localization industry. This is because Japan has enjoyed a vibrant import/export-based economy over the last 50 years, generating significant language translation demand between English-Japanese, German-Japanese, and Chinese-Japanese. Japan has the world’s third largest automotive and the biggest electronics manufacturing industries. In recent years, the country has emerged as a global leader in precision instruments, high-tech manufacturing, hybrid vehicles, and robotics. All of these economic activities heavily depend on global supply chains for systems and parts/components, calling for language translation services across the board. Combined with international marketing/sales efforts for the finished products, Japanese language translation requirements account for a significant portion of worldwide localization spend. According to industry studies, the annual Japanese translation spend is roughly $3.5 billion dollars and growing at a rapid pace. The biggest companies in terms of language translation spend include Toyota, Nissan, Honda, Panasonic, Sony, Fujitsu, Toshiba, Mitsubishi, and Canon among others. Compared to other European and Asian languages, Japanese per word translation rates are one of the most expensive due to higher labor cost and the fact that Japanese translating speed is generally slower.

Japanese Language Q&A

Why do Japanese translation reviews often produce more changes compared to other languages?

Within the localization industry, Japanese is known as one of the most difficult to translate among language service providers (LSP). Unlike most Latin alphabet-based languages that share similar sentence constructs and expressions, Japanese, as well as Chinese and Korean, are character-based languages that use very different grammar and sentence structures. This means the same English sentences can be translated into Japanese in a number of different ways. At the same time, there are many English words that simply do not exist in Japanese, making it even more difficult for verbatim translations. Finally, translations can sometimes be subjective with the choice of words and expressions. All of these factors contribute to make Japanese translation reviews more challenging compared to European languages. However, proactive terminology management and systematic implementation of J2450 quality metrics can help ensure the best Japanese language translation performance.


Can we translate into Chinese first and then convert the text to Japanese automatically because Japanese writing uses many Chinese characters?

Definitely not. Japanese and Chinese are two very different languages despite sharing common Chinese characters in their writing systems. The modern Japanese writing system uses a combination of Chinese characters called kanji, and 96 basic syllable characters called kana that consists of hiragana (native Japanese words) and katakana (borrowed foreign words or loanwords, as well as scientific terms.) Japanese has a very different pronunciation and grammar system than Chinese. There is no way to convert Chinese texts to Japanese automatically without going through a full translation process.


What is Japanese MTPE?

Machine translation (MT) powered with AI, and sophisticated computer algorithms are increasingly able to achieve substantial quality results translating text between English and Japanese automatically. MT is fast, scalable, and most importantly, very inexpensive. This is why more and more companies are looking into MT as an integral component of their enterprise translation solutions. However, MT alone is still insufficient to translate the content used for customer communications. MTPE or machine translation post-editing is a process that first translates the Japanese texts with MT, and then uses professional Japanese linguists to proofread and edit the results for good quality output. Indeed, Japanese MTPE is a solution that’s already becoming a mainstream language production model.
