Boasting a 50% share of the number of multichannel cable TV-subscribing households in Japan

Jupiter Telecommunications (hereinafter "J:COM") is a Sumitomo Corporation group company and a facilitator of the group's media, ICT, lifestyle related goods and services business. J:COM was established in 1995, and now, more than 20 years after its founding, J:COM has dramatically developed into Japan's largest cable TV operator with the total number of subscribing households increased to 5.55 million, and has become a media company that leads the multichannel market.

At present J:COM provides 3.93 million households with cable multichannel broadcasting services, and boasts a 50% share of the number of households that subscribe to cable TV multichannel broadcasting services in Japan (as of October 31, 2019.) The company covers a service area that extends from Hokkaido to Kyushu, and has a total of 70 cable TV stations, which are affiliates of J:COM, that provide subscribers with local services.

Providing both upstream and downstream services in the TV value chain

J:COM's business features "one-stop triple play" service with a focus on CATV, which specifically refers to providing the following three core services in one package: cable TV service "J:COM TV", high-speed Internet service "J:COM NET", and high-quality fixed phone service "J:COM PHONE".

J:COM is strong particularly in the cable TV field, with the number of channels available to subscribers totaling 100 or more, including those featuring movies, dramas, sports, animation, music, variety shows and various other programs of all genres. In recent years, the company has been further enhancing its services to allow its subscribers to enjoy viewing cable TV programs in a more diversified manner, including the tablet service, in which subscribers use their tablets as a second TV screen, "J:COM On Demand," which allows viewers to choose the programs that they want from among 70,000 or more options whenever they want, and BS4K broadcasting service.

The company carries out both upstream and downstream businesses in the value chain, creating local-oriented channels and offering high-quality contents and media/infrastructure services.Also, it operates a total of 17 specialty channels, including "Movie Plus," the "GOLF NETWORK," and "J SPORTS."Furthermore, Asmik Ace, Inc.(a subsidiary of J:COM), a movie creator and distributor, engages in not only movie-related business but in rights business, dealing with purchase and copyright management of video contents mainly of animation, and in the largest scale VOD business in the paid-video distribution service in Japan.

Subscribers can view programs on 17 specialty channels through J:COM and other cable TV/satellite broadcasting services.

Taking on challenges to provide services in new domains

J:COM has been offering infrastructure services that are indispensable for people's daily lives, including TV, the Internet and telephone services. The company is in the process of expanding the types of infrastructure services that it provides to the public by adding mobile service (as the fourth core) and electricity service (fifth core) to the portfolio.

J:COM MOBILE, offered since October 2015, is an MVNO service (*) available from just 980 yen per month. J:COM MOBILE customers are entitled to free in-home setup support provided by J:COM staff. J:COM MOBILE offers count-free (excluded from the packet count) for users to view videos of their choice for free through J:COM On Demand whenever and wherever they want. Also, the app will allow customers to enjoy new audiovisual experiences, including watching a professional baseball game live outside their house, in addition to viewing CATV programs they have missed.

J:COM Electric Power represents the fifth core infrastructure service to be provided by the company. The electricity market has gradually become deregulated. Following the liberalization of retail sales of electricity to factories and large buildings in 2004 and to condominiums in 2005, J:COM, in cooperation with Summit Energy (a Sumitomo Corporation Group company with five power stations across Japan), began package sales of electricity to condominiums in 2012. After the retail electricity market is fully liberalized in Japan in April 2016, sales of electricity to all types of households became possible and the number of potential customers will increase accordingly. The number of households using the service is steadily increasing, and J:COM plans to expand its electricity services going forward.

J:COM MOBILE is currently selling the Galaxy A30. It features an organic electro luminescence display, a high-capacity battery, and is waterproof—everything you’re looking for in a smartphone is right here.

Sumitomo Corporation operates in a wide spectrum of business domains as an integrated trading company, and possesses integrated corporate strength. Summit Energy is engaged in the electric power generation business, while J:COM has a network that links households. The two Sumitomo Corporation Group companies are able to deliver electricity to a great number of households at low prices by fostering mutual cooperation.

J:COM will make use of the support ability unique to the company that takes root in local communities with an eye to providing easy-to-use mobile and electricity services to the public as one of its major goals for the future.

In addition, In April, 2017, J:COM started a new retail city gas service, “J:COM Gas Supplied by Osaka Gas”, as an agent of Osaka Gas Co., Ltd. In the Kansai area. Also, in May 2019, J:COM started to provide its retail city gas service in the city gas supply area of Tokyo Gas Co., Ltd.
