Before I explain in detail, lets put the Rule no.1 on table,
pack everything you need and do not plan to buy it in Japan, or else you might end up paying 3-5 times more than what you could have paid in India.
Cloths:
Depends on which season you are in, July - September is Summer season in Japan (please search net for other season),and its very very hot and Humid, like in Mumbai. So you need Cotton Shirts and Trousers for formal and Tees and Jeans for Weekends.
Launder is very costly, For a shirt, Hotel will charge 1100 Yen. I am going to another laundry which charge 550 yen to wash and Iron the shirt. it also varies on type of cloth, like cotton, linen etc.
Buying cloth is very expensive, unless you travel long distance to find some cheap shops.
I wash inner in the machine provided in the apartment. You can find good detergent on department shops, though I took two days to understand which one is for washing cloths
.
Black trouser and light color shirt is a trend here, but nothing strict. BTW most of Japanese love to be very well dressed, specially females (sometimes less dressed as well
).
If you plan to visit Mount Fuji or Mount Takao in summer, you might need some warm jacket. Its was chilling there this Saturday.
Also you need some good walking shoes, and you will have to do lots and lots of walking. I carried one pair of formal and one pair of Sude shoes
Also pack a portable but strong umbrella with you. You may need it anytime.
Toiletry:
if you are coming for short time, get enough with you, and for long term, it does not matter, you will have to buy from here. But lots variety are available, costly obviously.
Medicine
Carry all you need,all general and personal medication
Food
If you are a hard-core Non-Veg, this place is a heaven for you. if you are hard-core vegetarian, you will be dead with in a week, unless you know cooking and have time to do that (or you have lots of money for Indian Restaurant).
And if you are somewhere between above two, like me, You will have hard time.
Bottom line, this is not a place for vegetarians, so I carried lots of packed food(MTR) and Cup Noodles with me.
Also if you plan to cook, pack all the spices you need. You will not find anything other than salt,chilly powder, mustard powder in local departments. It took me two weeks to find Turmeric, found it in an Italian store in Shinagawa station, BUT, 620 Yen for 70 gm. So did I told you, PACK every thing from India.
For long term, there are some Indian stores around, but I have no idea.
Also there are some Indian restaurant as well. I tried one in Hakozaki owned by a punjabi from Jalandhar. Food was good but COSTLY. A full meal dinner for a person cost, 1700 yen, without drinks.
In shinagawa I found an India restaurant, charge 900 Yen for small meal and 1900 yen for full meal, and food does not taste like Indian.
Also McDonald is good for me. Chicken Burger with Large Fries and Medium Drink costs, 630 Yen, but fills the stomach very well. KFC serves bucket which is different than what we get in India.
At apartment, I am cooking rice, potato, Pasta, noodles etc some times. Pororoca is the department store where you can find vegetables. One single tomato cost 100 Yen, 4 medium size potato cost 198 Yen, 2 big size onion cost 150 Yen and similar prices. You can find lots of vegetable there.
There are lots of Japanese restaurant serving famous and good food from 600 yen to 1000Yen. So Non-vegies have no problem
Stationary
Carry whatever you need
Guides and Documents
Carry all essential document.
For travel guides/maps/routes, BUY it from India. Lonely Planet guide for Tokyo was around 600 Rs in India, here it is 2700Yen. So you know the message.
search Internet for all the railway/subway/monorail maps/JR Lines/Shinkansen(Bullet). I will share most of them in another post dedicated to transportation.
