lol watch out for those obachans and ojichans(old lady and old men) on the train and normal day life.. they will push u aside if ur in their way with elbows lol.. also depending on where u wanna go.. ikebukero in tokyo is pretty popular.. u would need the yamanote line to get there...
The Yamanote line does a huge circle so u can get it to shibuya, Harajuku, Shinjuku and Akihabara...As well as Tokyo station etc..
If you want bars, funky clubs, strip clubs etc.. Shibuya and Shinjuku are your main targets...i can lay down the scenes of each so its easier cause they sound the same
Shibuya - High end fashion brands, accessories its all there fashion wise... also many teeny bobbers hang out there(Aka Shibuya girls) Ayumi hamasaki shops there as well at the plaza called 609 or something newho. also a good place i hear is Gaspanic bar/club or watever.. but the problem is u have to keep ordering drinks and if u dont tip them they make weak drinks lol..
Shinjuku - Nice dinners,lunches and bars and nice gift shops there.. also a huge book shop there and on the 6th floor has english books so if u didnt get a guide book and u feel alittle overwhelmed head ther and pick one up
Harajuku - another fashion place but more for urban/used and other stylish clothes there.. really worth the trip
Akihabara - electronic town, anything and everything is there
Food:-
Keep in mind ur maccers and kfc fix like in aus is very different here.. lol i suggest ya dont worry about it.. its too expensive also its not as large as u think when u try a large..
Try eating at these places... Matsuya, Yoshinoya, Coco's Curry shop, Ramien Shop's..
Matsuya: is my fav out of all them.. its like very lush food at cheap prices also its instantly made really for you in less then 3mins plus they give u free miso soup, To order at Matsuya u will see a vending machine inside or outside depending on where u go, you put ur cash in and pick the dish u want then you will get a ticket and walk inside, sit down give them the ticket and foods ready!.... plus its open 24hrs so after a heavy drinking session at your local izakaya, matsuya isthe way to go..
Yoshinoya: same but doesnt compare.. the food isnt that hot.. plus theres not much too choose from also it doesnt give you free miso soup.. ordering food is near the same.. depending on where u want to go.. or it may not even have a vending machine and you tell them which one you want...
Coco's curry shop: Heres a good place to try japanese curry for the first time.. you pick which style of curry you want then pick the spicyness.. i always choose chicken katsu(chicken fillet) curry with 3 stars.. which is decent.. this curry shop is also open 24hrs or till 1 am i forgot.. the price is alittle more then the other two but for just trying it the first time its worth it..
Transport
Here is the most important rule about japan do not catch taxi's unless its really needed, the price for taxis is written on the side and if you dont know how far away your going ur gonna get charged a arm and a leg.. also dont open taxi's door, they can do it them selves same with closing .
best forms of transport in japan is only Train and buss.. beside its much easier and faster to get anywhere less hassle but only problem is knowing which way to go.. since many people get lost in the subways and trainlines in japan.. even japanese citizens get lost... but newho .. its pretty simple..
Bars and host bars
Yup, you ask for a bar in japan u will get directed to a host bar, where u pay insane amounts of cash to sit down with a girl/guy or two for a hr or so drinking and talking to them.... but what u really want some is some clubs or proper bars...So best places for you and your mates is a Izakaya its a japanese style bar.. where u sit on the floor drinking and eating all the japanese drinking foods.. tell ya.. Raw horse with soy&garlic is pretty delicious after u had some asashi beers lol..
So mate when u land in japan make sure u have already got transport from the Narita airport to ur hotel.. never catch a taxi if u havnt got arranged transport.. you want to start to research on trains now...
anyways mate, good luck in japan here .. i been here for nearly a year and im loving it..
if feel unsure on anything like helpful questions in japanese post here or pm me.. most of us in the land of the rising sun can help you mate..
cheers.. have a safe flight...
