Clothes for winter in Japan

Hi..my name is Man from Malaysia, actually I try to find more information about clothes for winter in Japan (Osaka) because I'm going there in January 2009. Basically I know nothing and please advise me. I try to imagine what type of clothes but unfortunately I'm failed to imagine cause my country don't have 4 seasons like Japan. Do provide me with a link if possible.

Warm trousers, a sweater and thick coat, gloves, a scarf and hat and good walking shoes. A lot depends on where in Japan you will be as the climate varies considerably from north to south and coast to coast

thank u Sira..

I'm going to Osaka..under JICA training program for about 21 days. So do I standby those clothes while in the plane or I can wear those clothes after I arrive at the airport...

can you all suggest what type of shoes should I wear?..I mean just ordinary shoes or special type shoes for winter?

I have a lot of questions to ask but I will ask it one by one..

by the way thanks in advance

Sneakers are fine. You will most likely do a lot of walking, so anything you can walk in comfortably that will keep your feet fairly warm.

As for whether you wear/take the clothes on the plane or not, it depends how cold you feel in the plane. Some planes are more strongly air-conditioned than others. I am currently on my way back from Australia to Japan (using the free internet to pass time during a 6 hour transit at Singapore Airport!) and I have a medium weight sweater that I was wearing on the plane. The airport and trains in Japan are well heated, but I am carrying another sweater and a scarf to put on when I leave the train in central Tokyo.
