This page discusses various Japanese internet companies and internet startups.
Public companies
Companies that have Initial Public Offering (IPO) on the Tokyo Stock Exchange, usually on the Mothers index.
Yahoo! Japan
- Launched in 1996 as a joint venture with SoftBank. Yahoo! held a 35% stake, while Soft Bank (through a variety of subsidiaries) held a plurality stake of 43%. Unlike the U.S. parent company of its namesake, however, Y! Japan has been extremely successful in Japan due to being operated like a traditional Japanese company instead of a western company (avoiding culture clash in the progress), and is the country's largest general internet services. Its primary business is in web search and online/smartphone advertisingnote , C2C/B2C e-commerce through Yahoo! Auctionsnote , travel/restaurant reservations, mobile gamedev, and other areas. They also have an ADSL/FTTH broadband reselling ISP called Yahoo! BB. At the peak of the dotcom bubble, shares of Yahoo! Japan reached 100 million yen ($100 million US) per share. Unfortunately, the dotcom burst hit Y! Japan hard, but SoftBank's continued investment in the company (one of Masayoshi Son's few direct investments in Japanese tech companies), plus the U.S. parent company's successful investments in Alibaba, have allowed them to make a comeback, and now they're closing on 1 trillion yen in revenues.
Rakuten
- Rakuten is best known for its C 2 C e-commerce platform Rakuten Ichiba, and a billion other things: travel (Rakuten Travel), e-books (Kobo), messaging apps (Viber), payment gateways (Rakuten Checkout), NFC contactless payment platforms (Rakuten Edy). They're also the main partner for FC Barcelona, one of the few soccer partnerships by companies in baseball-mad Japan. Founder Hiroshi Mikitani is the third richest person in Japan, behind Uniqlo founder Tadashi Yanai and SoftBank founder Masayoshi Son.
