Quality

Quality

Quality of electrical appliances and their cordsets in Japan is overseen by the PSE DENAN law from the Japanese Ministry of Economy, Trade and Industry (METI), formerly known as DENTORI.  The DENAN symbol, PSE diamond or JIS approval is required on electrical products in Japan.  All Morvan Trading’s Japanese power cables are independently tested by the Japan Electrical Safety & Environment Technology Laboratories ‘JET’ test-house, and our approved products either carry PSE or PSE JET markings.

A Japanese medical or hospital grade plug is specified in JIS T 1021 and JIS C 3005, which we offer in grey, but these are not a mandatory requirement in hospitals.

Where are they used?

Where are they used?

Japanese mains voltage is 100V AC, but at two discrete frequencies: northeastern Japan on the Tokyo grid (including Yokohama, Tohoku, Hokkaido) uses 50Hz, while southwestern Japan on the Osaka grid (including Nagoya, Kyoto, Hiroshima, Shikoku, Kyushu) uses 60Hz.  Normal appliances should not be affected, but electrical motors, clocks and timers may run faster or slower; more modern equipment is now designed to run on either frequency.  In the early days of electricity, a German 50 hertz generator was imported by Tokyo Electric Light Co in 1895, while a year later and 500km away Osaka Electric Lamp brought in a 60 cycles generator from the USA; slowly the rest of the country was wired on the two circuits until it was too late and too expensive to standardise.

Japanese JIS 8303 – Japan standard – an overview

The IRAM 2073 standard – an overview

Japan originally used North American type 15A plugs, but has since developed its own standard.  The main differences are that manufacturing tolerances for the plug are stricter, and metric mm2 VCTF cable is used.  Plugs and cables must also be Japanese-approved.  A 20A plug similar to the American one is also used.

Pre-2005, older Japanese power outlets had no requirement for a third receptacle to accept a plug with earth pin; earthing is via a special earth post or the screw that holds the faceplate.  For this reason there exist special Japanese 2 pin plugs with a flying earth lead, that can be connected to the earth screw with a crocodile clip or screw-down terminal.  Morvan can also supply adaptor plugs.
