1. Several important technological inventions originated from Japan in the late 20th century, including the floppy disk, compact disc, Walkman portable music player, calculator, digital SLR camera, video cassette, and camcorder. 2. These inventions revolutionized data storage, music playback, photography, video, and home entertainment. The floppy disk, first developed in 1952, was a precursor to later storage devices and the standard into the 1970s. Sony's compact disc format, introduced in 1976, became the dominant way people listened to music. 3. Japan also pioneered innovations in portable devices with the Walkman in 1978 and consumer electronics like the first quartz wristwatch in 1969. These

1. Japanese
Technological
Inventions

2. 1. Floppy Disks
The floppy disk used to be the choice of media before the
introduction of the compact disc and USB pen drives. This
once very useful invention was developed by Japanese Dr.
Yoshiro Nakamatsu in 1952 and was large – 8 inches or
200 mm in diameter. It was commercialized in 1971 and
was adopted by IBM

3. 2. The Compact Disc
The compact disc (CD)
was the choice of storage
for media.
Sony first demonstrated
the use of audio on
compact disc in 1976 are
perhaps the most
important technologies to
come out of Japan.
The optical disc remains
one of the modern world’
s most ubiquitous
inventions

4. 3. Portable Music Player
Before the iPod, portable
music was carried in
cassettes and listened to
on the Walkman,
invented by Nobutoshi
Kihara in 1978.
The invention was the
standard for portable
music for almost 20 years

5. 4. Calculator
Although the first so-
called ‘compact’
calculator was also made
in Japan, it wasn’t until
1971, helping to
conserve battery and
brain power around the
world.

6. 5. Digital SLR Camera
The first known digital
camera with single-lens
reflex elements was the
Sony Mavica
Japanese-developed,
full-fledged digital SLRs
started to the popular
choice among
professional
photographers

7. 6. Video Cassette
The video cassette and VCR, both
Sony creations made available in
1971, represented the start of a
new era in home entertainment.

8. 7. Camcorder
an electronic device that
combines a video camera
and a video recorder into
one unit; typically for out-
of-studio consumer video
recording, Commercial
digital recording was
pioneered in Japan by
NHK and Nippon
Columbia, also known as
Denon, in the 1960s. The
first commercial digital
recordings were released
in 1971

9. 8. Quartz Wristwatch
Released in 1969, the
Seiko Astron was the
world’s first quartz
wristwatch. Quartz
technology represented a
substantial upgrade over
old-fashioned mechanical
watches

10. 9. Flat-Panel Display
a pocket television
released in 1982. The
FD-210′s display was a
paltry five centimeters,
but the technology
involved was impressive
and paved the way for
the home entertainment

11. 10. Robotics
The world's first android, DER 01,
was developed by a Japanese
research group,
The Actroid is a humanoid robot
with strong visual human-likeness
developed by Osaka University
and manufactured by Kokoro
Company Ltd
ASIMO - Advanced Step in
Innovative MObility
humanoid robot designed and
developed by Honda
allowing for increased joint
flexibility and a smoother, more
human-like walking motion
