Country
Japan
Address space that resolves to Japan, and who operates it.
Where the space resolves, which is an estimate for the block, not a fix on any device. A network can hold space in many countries at once, so the same space is counted on more than one country page.
What this tells you
- 1,611 networks hold address space located in Japan, run by 393 operators we can group by name.
- An estimated 108,075,384 people browse from Japan, over a 60 day window. Counted where the users are, whatever registry their network belongs to.
- The largest operator we can identify by name here is SoftBank Corp., holding 20% of the IPv4 space.
- VPN exit infrastructure here belongs to Apple Private Relay, TunnelBear, NordVPN and 22 other providers. An address in Japan is not necessarily a person in Japan.

Organisations holding space here
Registered organisations account for 27% of this country's IPv4 space and 44% of its IPv6 space. The table below divides that space. Registered holders come from the bulk whois that RIPE, APNIC and AFRINIC publish. ARIN and LACNIC do not publish theirs, so space held in North and South America is largely unattributed here.
| Organisation | IPv4 share | IPv6 share | |
|---|---|---|---|
| SOFTBANK Corp. | 81% | 90% | |
| JCOM Co., Ltd. | 9% | <0.1% | |

Anonymizer signals
Flagged space covers 9% of this country's IPv4 space and 0.6% of its IPv6 space. The table below divides that space.
| Category | IPv4 share | IPv6 share | |
|---|---|---|---|
| Open proxy | 96% | 89% | |
| Datacenter | 83% | 74% | |
| VPN | 10% | 17% | |
| Tor exit | <0.1% | 0.2% |
One address can carry more than one of these, so the rows add up to more than the space they cover.
VPN providers with exits here
Space published by a named VPN provider covers <0.1% of this country's IPv4 space and <0.1% of its IPv6 space. The table below divides that space. That counts only what providers publish as their own exits. Space merely associated with VPN use is wider, and is counted under Anonymizer signals above.
| Provider | IPv4 share | IPv6 share | |
|---|---|---|---|
| Apple Private Relay | 70% | 100% | |
| TunnelBear | 18% | - | |
| NordVPN | 6% | - | |
| ProtonVPN | 2% | - | |
| Private Internet Access | 0.8% | - | |
