Overview

GLOVA (Glova Corporation; Japanese: 株式会社グローヴァ) is a Japanese business-to-business language-services company headquartered in Chiyoda, Tokyo. It provides human translation, interpretation, and corporate language training, primarily to companies and public-sector organizations in Japan. According to its official website, it has served around 20,000 clients, including government agencies and major corporations, supports more than 30 languages, and offers translation priced from 8 yen per source character. Its interpretation service covers assignments across Japan as well as overseas, including arrangements for local native-language support. Its corporate language-training service is built around a proprietary "TIY method" and is described as having been delivered to more than 1,000 companies. GLOVA was established in January 2000 as an in-house venture within Nova Corporation (株式会社ノヴァ), a well-known Japanese English-conversation school operator. In 2001 it acquired a subsidiary, Kaigai Hoso Center (株式会社海外放送センター), which was engaged in corporate language training. In 2004 GLOVA became a wholly owned subsidiary of Rosetta Corporation (株式会社ロゼッタ), a company originally founded around machine translation. Rosetta listed on the Tokyo Stock Exchange Mothers market in 2015, and in 2019 GLOVA absorbed Intermedia Corporation (株式会社インターメディア), which had also been a Rosetta subsidiary. In 2021 Rosetta changed its corporate name to Metareal Corporation (株式会社メタリアル), which remains GLOVA's parent. GLOVA's business is organized into three main pillars: translation, interpretation, and training. The translation business handles documents and content for corporate and public-sector clients across more than 30 languages. The interpretation business dispatches interpreters to locations throughout Japan and can also arrange overseas interpretation, including support in local native languages. The training business provides customized corporate language programs based on the company's TIY method. The company also runs seminars and lecture courses, including Chinese-language business seminars and reading courses led by advisor Masamichi Mizuma, an emeritus professor of Reitaku University, as announced on its website. As a wholly owned subsidiary of Metareal, GLOVA operates within a group that combines human language services with language-technology businesses. Its official site presents it as a partner for global business, using the tagline "win in global business with language." The company recruits both headquarters staff and translators, reflecting the dual nature of its operations as a service provider and an employer of language professionals.

History

GLOVA was established in January 2000 as an in-house venture within Nova Corporation (株式会社ノヴァ), a major Japanese operator of English-conversation schools. The new company was created to serve corporate clients with language-related services, distinct from Nova's consumer-facing language instruction business. In 2001, GLOVA acquired Kaigai Hoso Center (株式会社海外放送センター) as a subsidiary. That company's business consisted of corporate language training, which became one of GLOVA's core service lines alongside translation and interpretation. In 2004, GLOVA became a wholly owned subsidiary of Rosetta Corporation (株式会社ロゼッタ), a company that had been founded with machine translation as its main business. This placed GLOVA within a group that combined human language services with language technology. Rosetta later listed on the Tokyo Stock Exchange Mothers market in 2015, giving the group a public-market presence. In 2019, GLOVA absorbed Intermedia Corporation (株式会社インターメディア) through a merger. Intermedia had also been a subsidiary of Rosetta, and its absorption consolidated group language-service operations under GLOVA. In 2021, Rosetta Corporation changed its corporate name to Metareal Corporation (株式会社メタリアル). GLOVA has continued to operate as a wholly owned subsidiary of Metareal, providing translation, interpretation, and training services. Its official website describes a client base of around 20,000 companies, including government agencies and large corporations, support for more than 30 languages, and translation pricing starting at 8 yen per source character. The site also highlights a proprietary TIY method for corporate language training and a track record of more than 1,000 corporate training clients. In recent years, GLOVA has also promoted seminars and courses, including Japan-China business seminars and Chinese reading courses led by its advisor Masamichi Mizuma, an emeritus professor of Reitaku University. These activities reflect the company's continued focus on practical business language skills, particularly for Japanese corporate clients working with China.
