世論 What Japan Thinks

japan.internet.com recently published a survey conducted JR Tokai Express Research on the use of home networking. They interviewed 330 people from all over the country to find out their views. 60.6% of the sample was male; age demographics were 20.3% in their twenties, 31.2% in their thirties, 27.9% in their forties, 15.5% in their fifties, and 5.2% in their sixties.

My personal experience with “wartraining” (like wardriving, only from the train!) is that on my ride home I can pick up about 60 or so open wireless access points according to NetStumbler, the bulk of them being Yahoo BB! wireless routers in their default configuration. Sadly this survey (or at least the free preview that I have translated) did not ask any security-related questions.

Q1: At home, how many computers, including games machines, do you have? (Sample size=330)

No machines	4.5%
One machine	39.4%
Two machines	27.6%
Three machines	13.9%
Four or more machines	14.5%

Q2: At home, are your computers (including net-enabled games machines) connected together by a LAN? (Sample size=330)

Yes, connected by LAN (to Q3)	41.5%
No, don’t have any machines	2.4%
No, just have the one machine	32.7%
No, have many machines, but not networked	22.4%
Don’t know	0.9%

These numbers don’t quite seem to agree with Q1! I think that some people with just one machine but a LAN may have chosen the “Yes” answer.

Q3: Do you use a wired or wireless LAN? (Sample size=137)

Wired LAN	51.8%
Wireless LAN	39.4%
Both wired and wireless	5.1%
Other	0.6%
Don’t know	2.9%
