1. Background:

2. Purpose:

• provide solid statistics on ISP traffic as inputs for operators and policy makers

ISP Backbone Traffic in Japan

1. We are collecting month-long aggregated traffic logs for different traffic groups from 9 major ISPs in Japan twice per year, in May and November, in order to analyze the macro-level impact of residential broadband traffic. These traffic groups are carefully selected to be summable, and not to count the same traffic multiple times.
2. The participating ISPs are BIGLOBE, IIJ, JCOM, KDDI, Nifty, NTT Communications, NTT Docomo(former NTT Plala), Optage, and SoftBank (former Softbank Telecom and fomer Softbank BB).
3. More information is available from:

• Traffic measurement from Japanese ISP backbones

IIJ Broadband Traffic Reports
