Communications Usage Trend
Survey in 2005 Compiled
MIC has compiled the "Communications Usage Trend Survey" as of the end of CY2005 in order to grasp the
usage trends in telecommunications and broadcasting services within households (households and household
members), companies (enterprises) and offices (establishments).
[Highlights of the survey results]
The number of Internet users via mobile terminals has been increasing further, surpassing those via personal
computers (PCs) for the first time.
With respect to terminals for accessing the Internet by individual users, the number of Internet users via
mobile terminals, including cellular telephones, increased by 10.98 million from the end of the previous
year (an increase of 18.8 percentage points over the previous year) to 69.23 million, surpassing those via
PCs (66.01 million, an estimated figure) for the first time. This shows a further increase in the number of
Internet users via mobile terminals.
More than a half of the Internet users (57.0%, or 48.62 million, of the total number [85.29 million],
estimated figures) are using both personal computers and mobile terminals.
The number of Internet users subscribing to broadband access networks continues to be on the rise.
When looking into the ratio of each broadband network, while the ratio of fiber-optic circuits has been
increasing, that of digital subscriber lines, or DSL, recoded a decrease for the first time.
The number of broadband access network users increased by 4.6 million (an increase of 10.8
percentage points compared to the figure as of the end of previous year) to 47.07 million (an estimated
figure), showing a continuous increase in the number of broadband users, or reaching 55.2% to the total
number of Internet users.
About two-thirds of households have access to the Internet via PCs (65.0%) and 68.1% of corporate
Internet users have subscribed to broadband access network services.
With regard to types of broadband circuits to which residential users' PCs are connected, while the
usage ratio of fiber-optic circuits grew from 6.1% to 14.8%, that of DSLs decreased from for the first time
from 39.2% to 34.2%. The same trend was seen in companies and offices.
Internet users have been continuously increasing.
The number of Internet users who have accessed the Internet in 2005 reached 85.29 million (an
estimated figure), increased by 5.81 million (a 7.3 percentage point growth over the previous year).
Thanks to the increase, the population coverage ratio of Internet users increased by 4.5 percentage points
to 66.8% (an estimated figure).
The digital divide between age groups still exists.
Differences in the usage rates for age groups, annual income groups, gender groups and sizes of cities
were narrowed in comparison with those in the previous year. However, the differences in the usage
rates for the age groups of their 60s or older and younger age groups are still remarkable (e.g., a
difference of 20 percentage points between their 50s and their early 60s).
When comparing the usage rate for cellular telephones with that for PCs, that for cellular telephones is high.
The PC usage rates extremely differ by age groups.
The cellular telephone usage rate (71.9%) exceeds the PC usage rate (56.7%) by 15 percentage
points, as is seen by age groups. In particular, the cellular telephone usage rate for the age group "ages
between 6 through 12" overwhelmingly exceeds the PC usage rate by 37 percentage points.
The cellular telephone usage rates for their 20s through 40s surpass 90%, even for their late 60s
exceeds 50%. On the other hand, the PC usage rates for their 20s through 40s exceed 70%, that for
their 50s is 55%, and that for their late 60s is 22.7%. With respect to the digital divide by age groups,
since skills and knowledge are needed to operate PCs, the older the age group grew, the lower the PC
usage rates decline.
Although IP telephony services have been introduced into corporate users, the number of residential IP
telephony users has slowed down in the growth rate.
The corporate usage rate for IP telephony services has grown by 11.6 percentage points year on year to
39.4%. On the contrary, the residential usage rate for IP telephony services has slightly increased by 2.3
percentage points to 15.0%, showing a stagnant growth rate lower than that of the year before (an
increase of 5.4 percentage points).
Some measures for protecting personal information have been taken by corporate users on a swift pace.
The corporate user rate of information and communications networks who take some measures for
protecting personal information have grown by 16.7 percentage points over the previous year to 73.2%,
indicating that measures for protecting personal information have been taken by corporate users on a swift
pace. Of such measures, "improved training at office" recorded the highest rate of 45.7%, followed by
"appointment of a chief information officer (CIO)" (41.4%).
[Outlines of the survey]
The "Communications Usage Trend Survey," which is composed of the following three sections:
"Households/household members," "Companies (enterprises)," and "Offices (establishments)" has been
conducted annually since 1990* as a statistical survey authorized by MIC in accordance with the Statistical
Report Coordination Law. The survey on "Companies (enterprises)" was conducted in 1993 as the annual
survey (except 1994), and "household members" was added in 2001.

(2) Internet users as a proportion of the population (householders)
The number of people who used the internet in the past year was 85.29 million,
up 5.81 million (7.3%) since the end of last year. Continuing growth in absolute
user numbers was matched by a commensurate increase in the proportion of
internet users relative to the total population, which rose 4.5% to 66.8%.

Notes
1. Internet user numbers shown here are projections based on the number of survey respondents aged six and
over who accessed the internet during the past year, from any device (including computer, cell phone/PHS, PDA
and game console) and for any purpose (including private, school-related and work-related).
2. The figure for internet users as a proportion of the population is an estimate calculated by dividing the total
population as of October 2005 (127.71 million, the intermediate projection given by the National Institute of
Population and Social Security Research in Future Population Projections for Japan) by the projected number of
internet users (85.29 million).
3. Figures for 1997 to the end of 2000 are quoted from the Communications White Paper. Figures for 2001 to the
end of 2005 are taken from the Communications Usage Trend Survey.
4. The survey sample in 1999 was respondents aged 15 to 69. This was expanded to respondents aged 15 – 79
in 2000, then to all respondents aged six and over from 2001 to reflect increasing internet usage by school-age
students. As a result of these demographic changes, it is not always possible to make direct comparisons
between survey results from different years.

(3) Internet usage by device (householders)
The number of personal internet users employing mobile terminals (chiefly cell
phones) to access the internet rose by a further 10.98 million (18.8%) to reach
69.23 million, surpassing internet access by computer (66.01 million) for the first
time and indicating continued growth in the trend towards mobile internet usage.
The majority of internet users (48.62 million or 57.0%) access the internet from
both computers and mobile terminals; the number of users who access the internet
from a computer only fell by 5.21 million.

(4) Demographic breakdown of internet usage (householders)
Although variation in internet usage rates according to age, gender, city size and
household income has decreased since the previous survey, internet usage rates
are still much lower among people aged 60 or more — for instance, there is a
difference of 20% between the 50 – 59 age group and the 60 – 64 age group.

(5) Impact of demographic factors on internet usage (householders)
Among the demographic characteristics considered in the survey, age group had
the greatest impact on internet usage followed by household income, while city
size and gender were of negligible significance.
The “12 and under” and “50 and over” age groups had a negative influence (i.e.,
respondents in these age groups were less likely to use the internet), with the “60
and over” age group having a particularly strong negative influence. Looking at
household income, the “less than ¥6 million” categories had a negative impact,
while the “¥6 million and over” categories had a positive impact.

Note: The impact rating is determined via multivariate analysis using type II quantization*. A positive figure
indicates a factor that promotes internet usage, while a negative figure indicates a factor that hinders internet
usage. The higher the number, the greater the impact.
* Type II quantization is a form of multivariate analysis involving the use of qualitative data for both predictor and nonpredictor variables. Here, the impact in each category (called the category score) is calculated with internet usage as the
non-predictor variable and the demographic characteristics as the predictor variables.

(6) Frequency of internet usage (householders)
Of those householders who access the internet at least once a day, over half
(55.3%) do so using a cell phone, while 43.9% use a computer, a difference of
11.4%.
Cell phones are preferred over computers across all age groups, particularly in
the younger age brackets (13 – 19 and 20 – 29), where the proportion rises to over
60%. The proportion for computers is lowest in the 13 – 19 age bracket at 36.2%,
but relatively constant at around 40% from 20 to 59 years of age. Few children
aged 6 – 12 use the internet on a daily basis, with the cell phone and computer
figures both in the range 14% - 15%.

(7) Purpose of internet usage (householders)
When accessed from a cell phone, the internet is overwhelmingly used for
contacting and/or sending information to friends and colleagues via email or
equivalent (69.5%); the next most common uses are downloading or listening to
digital audio content (26.2%) and viewing news and weather forecasts (25.1%).
These findings indicate a strong preference for obtaining and exchanging
information while in transit. When accessed from a computer, meanwhile, the
internet is generally used for obtaining information on products, services,
businesses and retailers (55.4%), contacting and/or sending information to work
associates and friends (54.4%), and viewing news and weather forecasts (50.2%).
Thus, computer-based internet usage is spread among various categories,
whereas mobile internet usage tends to be concentrated in one category.
Cell phones are used more than computers in two categories only: contacting
and/or sending information to friends and colleagues, and accessing digital
content. In all other categories, computers are used more than cell phones,
particularly for obtaining information on products and services and viewing news
and weather forecasts.

(8) Usage of e-commerce (companies)
Some 30.9% of companies use e-commerce in the form of procurement and
sales over the internet. Very large companies with 2,000 or more employees are
more than twice as likely to use e-commerce as small companies with 100 – 299
employees (60.7% versus 27.0%).

The majority of companies (85.6%) have their own websites, which are
increasingly used as a means of disseminating information about the company.
Almost 100% of very large companies with 2,000 or more employees have a
website; the percentage of smaller companies with websites is less, but the figure
is steadily rising and closing the gap on larger companies.

Usage of telecommunications devices
(1) Cell phone vs. computer usage (householders)
Overall, cell phone usage is more than 15% higher than computer usage (71.9%
versus 56.7%) in all age groups. The only exception is the 6 – 12 age bracket,
where computer usage is approximately 37% higher than cell phone usage.
Cell phone usage is over 90% in the 20 – 49 age bracket, and still around 50%
in the 65 – 69 age group. Computer usage is over 70% in the 20 – 49 age bracket,
falling to 55% among 50 – 59 year olds and 22.7% among 65 – 69 year olds.
These results indicate that computers, which are more difficult to master than cell
phones, have created a significant digital divide between generations.
Viewed by gender, city size and household income, the difference in usage rates
was greater for computers than for cell phones. As household income rises, the
discrepancy between computer and cell phone usage narrows.

(2) Impact of demographic factors on cell phone and computer usage
(householders)
Among the demographic characteristics considered in the survey, age group had
the greatest impact on both cell phone and computer usage rates, followed by
household income. In general, demographic factors had a greater impact on
computers than on cell phones.
The “12 and under” and “50 and over” age groups had a negative influence (i.e.,
respondents in these age groups were less likely to use computers), with the “60
and over” age group having a particularly strong negative influence. Looking at
household income, the “less than ¥6 million” categories had a negative impact.
These findings are similar to the trends for internet usage.

(4) IP phone penetration (companies/households)
The industry IP phone penetration rate rose 11.6 points since last year to reach
39.4%, or roughly 40% of large companies. IP phone systems are used mainly for
calls between different company locations (27.4%), as well as internal calls
(25.7%) and external calls (21.9%).
The household IP phone penetration rate rose only 2.3 points to 15.0%, a
slowdown in growth from last year’s 5.4 points.

(5) Penetration of ubiquitous technology* (companies)
The highest penetration rate for ubiquitous technology was networked devices
such as cameras and sensors (12.9%), followed by non-contact IC cards (10.9%),
positioning systems such as GPS and cell phones (4.5%) and RFID tags (2.8%). In
each of these areas, at least 10% of companies were planning to introduce the
technology in the near future, suggesting a further increase in penetration rates.
Company size has a significant effect on penetration rates. Very large
companies with 2,000 or more employees have higher usage rates — for example,
34.5% for networked devices and 44.5% for non-contact IC cards, compared to
just 10.9% and 7.3% respectively for small companies with 100 – 299 employees.

57.0% of households with two or more computers employ a home LAN. This
figure is up 5.0% from last year, although growth in LAN usage has dropped to
less than half the previous increase of 11.4%.
Roughly half the home LANs are configured using cable only, although growth in
cable LANs has clearly levelled off (0.7% this year, 1.0% last year). Growth in fully
wireless LANs has plummeted from 5.6% last year to just 0.8% this year, while
LANs configured using a combination of cable and wireless components have
increased by a relatively solid 3.5%.

(2) Internal networks (companies)
The proportion of companies with internal networks has remained relatively
constant in recent years, and this year was no different at 89.6%.
Larger companies are more likely to have internal networks deployed throughout
the company (96.0% of companies with 2,000 or more employees versus 65.3% of
companies with 100 – 299 employees). Smaller companies are more likely to have
internal networks that reach only certain part of the company, which accounts for
the lack of company-wide networks.

(4) Network installation (companies)
Two-thirds of companies (65.2%) chose to outsource part or all of the work
involved in construction and installation of their corporate networks.
Looking at the effect of company size on outsourcing, 63% of companies with
100 – 299 employees used outsourcing. This figure increase to 74.2% for
companies with 300 – 499 employees but declines thereafter, reaching a low of
64.2% for very large companies with 2,000 or more employees. Larger companies
are also more likely to perform the entire installation process in-house (i.e., with no
outsourcing).

(4) Safeguarding privacy (companies)
Following the enactment of the Privacy Act on April 1, 2005, the proportion of
companies using networks (both internal and external, including the internet) that
have taken steps to safeguard the privacy of personal details rose to 73.2%, an
increase of 16.7% since last year. Meanwhile, the proportion of companies with no
privacy safeguards fell from 34.5% to 18.0%, indicating a growing awareness of
the importance of personal information security.
Larger companies are more likely to have privacy safeguards in place (around
90% of companies with 500 or more employees compared to around 70% of
companies with 100 – 299 employees).
The most common privacy safeguards are internal training programs (45.7%).
The next three most common responses all increased significantly from last year:
appointing Privacy Officers (41.4%), formulating privacy policies (29.7%) and
