Naigai Publishing Co., Ltd.

Naigai Publishing Co., Ltd. (株式会社内外出版社) is a Japanese publishing house headquartered in the Higashi-Ueno district of Taito-ku, Tokyo. It was established in 1959 in connection with the launch of its flagship car magazine, Monthly Jikayousha (『月刊自家用車』), and has since built its business around hobby and leisure titles — most prominently automobiles, motorcycles and fishing. The company describes itself as a 'downtown' (shitamachi) enterprise rooted in the culture of Ueno, and frames its corporate mission as 'pleasing people and becoming happy,' with a stated emphasis on human capability and a small, free-flowing organization. Its publishing output spans several long-running magazine brands. In the automotive field these include Monthly Jikayousha, Auto Mechanic, the used-import-car title Yushu Chuko-sha Joho, STREET VWs and Kousoku Yuen Deluxe. In motorcycling it publishes Young Machine, BiGMACHINE and Moto Touring. In fishing it publishes Lure Magazine and its spin-offs, Iso-zuri Special and Chinu Club. The company also issues mooks and special editions such as WITH HARLEY and INDEPS, and it accepts commissions for corporate and self-published books. Beyond periodicals, Naigai Publishing operates a brand business that develops products and services derived from its content, and a media business that continues to deliver information through channels suited to the times. Its books business covers a range of genres intended to enrich culture. The company is privately held, with a stated workforce of about 50 employees, and is led by representative Kiyota Meijin. Its head office is in the Sunfield Building in Higashi-Ueno, a short walk from Inaricho, Ueno and Shin-Okachimachi stations. In 2026 the company announced that its founding title, Monthly Jikayousha, would cease print publication and move to a digital edition, reflecting the broader shift in Japanese hobby publishing from print magazines toward digital and branded content.

Naigai Publishing Co., Ltd. was established in 1959, the year its founding title, Monthly Jikayousha (『月刊自家用車』), was launched. The magazine gave the young company its initial identity as an automotive publisher, and cars remained a core pillar of its catalogue for decades. Over the following decades the company broadened into adjacent hobby and leisure fields. In motorcycling it built a stable of titles including Young Machine, BiGMACHINE and Moto Touring. In fishing it developed Lure Magazine and related titles such as Lure Magazine River, Iso-zuri Special and Chinu Club. Its automotive line expanded beyond Monthly Jikayousha to include Auto Mechanic, the used-import-car title Yushu Chuko-sha Joho, STREET VWs and Kousoku Yuen Deluxe. It also experimented in other genres, including the radio-controlled car magazine RC Car Sports (2005–2009) and the fashion titles CHOKi CHOKi and CHOKi CHOKi girls, though these were later discontinued. Lure Magazine River illustrates the company's willingness to launch, pause and revive titles: it was first published in April 2010, suspended in April 2011, and revived in November of the same year, positioned as a successor to Geibunsha's Gijie. Lure Magazine Salt, a saltwater spin-off, ran until its February 2024 issue, released on 21 December 2023. By the 2020s the company presented itself as more than a magazine publisher. Its official site organizes activities into a brand business that creates and offers new value derived from its content, a media business that delivers information through media suited to the times, and a books business spanning many genres and offering corporate and self-published book services. It also articulates a CSR stance as an 'impression-creating company' (感動創造企業), tying social responsibility to quality environments and good human relationships. A significant turning point came in 2026, when Monthly Jikayousha — the title that had defined the company since its founding — ceased print publication and moved to a digital edition. The change underscored the migration of Japanese hobby publishing from print periodicals toward digital and branded content, a shift Naigai Publishing has embraced through its media and brand businesses. The company remains privately held, headquartered in the Sunfield Building in Higashi-Ueno, Taito-ku, Tokyo, with a stated staff of about 50 and Kiyota Meijin as its representative.
