Top 20 of Japan’s most valuable web companies
The following list shows an up-to-date list of Japan's most valuable web companies by market capitalization. It's interesting to see 6 of them are large-cap (with 2 being very close). But 3 of these companies rather belong to the realm of financial services (the list includes companies, which are not exclusively engaged in Internet-related business).
The data comes from Netindex. Netindex offers an English version, which is not working at the moment.
I included English links whenever possible. No responsibility is taken for the correctness of this information.
