Things to take note of before going:

1. There isn't any rubbish bin / trash can in the streets in Japan (or at least, where I've been to in Tokyo). It is advised to carry a small backpack with you and have one or more recycled plastic bags in it so that you won't have to carry your trash on hand like a fool.
2. Bring a jacket or cardigan because it's kinda cold at night outside in May!! 
3. Bring more than one power adapter because one is never enough, really.
4. One small luggage is NOT enough if you want to buy snacks back (Note to self: Oreo soft cookie is a MUST to buy lots of) 
5. Pack light. Bringing extra snacks from home is not necessary. An onigiri or a donut from convenience stores costing slightly over 1SGD is plenty enough as a snack if you're hungry.
6. People working at subway station counters may have trouble understanding English sometimes so do your job in knowing which train lines to take beforehand.
7. Idk why online sources told me that meals in Japan cost at least over 10SGD because you can get good ramen for around 8SGD. Maybe they were talking about high-class restaurants or something.
8. Carry cash on hand - I've heard that lots of stores in Japan do not accept foreign cards or something but I don't use cards anyway so cash and coins are good for me.
9. Get Suica/Pasmo cards. They work like ez-link cards and you can top them up at machines with their logos. They only work in Tokyo I think. You can use them in random convenience stores and at vending machines too which is pretty awesome.
10. Getting Internet if you don't live there is kinda a pain in the ass because most wifi outside requires password except for the ones provided in train stations or your hotel etc. Rent a pocket wifi or buy a data card because having a working Google map can be very important if you don't know your way!!!
11. Idk what else

Took ANA to Tokyo!

Food on plane was awesome (and a little too much haha) and the triangular mash of greens and yellows was actually egg mixed with spinach I think. It was pretty good, surprisingly.

Fluffy morning clouds!!

Finally reached Japan and this was the first photo I took *facepalm* Was queuing up for the limo bus that would get us and our luggage from the airport to our hotel.

Nice weather, nice colours :') In Shinjuku where we stayed @ Shinjuku New City Hotel.

You gotta drop by 7-11 or any random convenience store during your trip!!! Look at these precious onigiri and sushi! The variety ahhh :')

Super crowded subway station. It was insane it felt like there were a million different exits we almost got lost trying to look for the place where we can purchase our Suica cards.

First meal in Tokyo :') The ramen was good, the broth was great but the noodles were a little too idk, thick? I, who usually finishes food faster than my female friends, couldn't finish the ramen... it was too filling omg. At that point I was wondering about the people I've seen on online forums complaining about the small servings of food in Japan and I was like, seriously?

Gyoza from the same ramen restaurant!

Got some random drink from a vending machine. Soy milk tea tasted interesting I guess. Can't get enough of those vending machines and their random drinks! :^)

Bought hi-chew cola sweets just because there's a Haikyuu!! pouch that comes along with it... I don't even like sweet stuff *sweats*

Day 2 in Tokyo! View from our hotel room on the 14th floor :) I love how it looked all sunny and burning outside but when I put my hand out it was super cooling.

Plain udon with egg for breakfast

Cool station photo while we were waiting for the train to Harajuku.

Outside Meiji Shrine

Okay so you have to cleanse yourself before entering the shrine (there were instructions written in both Japanese and English)

It was a really long walk into the shrine from its entrance

Apparently people often have wedding ceremonies / wedding photos taken in shrines and we happened to witness it!

Write your wishes and hang them up at 500￥

Saw this mother and her little daughter in kimono! Everyone was chasing the little girl trying to get photos of her lol

Random selfie with Weiyan at meiji shrine entrance :v

My outfit of the day! You can't really see it but I was wearing socks with polar bear prints haha

Headed to Takeshita Street In Harajuku after that. I love the crowd!

Mandatory crepe-in-hand photo in streets in Japan. It was too sweet for me though. Now that I think about it... This crepe was probably my lunch for that day

Merch stores are heaven look at all these Haikyuu!! merch like wow. Just wow.

Random bubble tea cuz we got thirsty or something I can't remember.

They have a Calbee shop how cool is that \o/

In the process of producing awesomeness

Random station photo in Harajuku

Hachiko statue in Shibuya!

Famous Shibuya Crossing. Did I mention that I love how you can cross the road diagonally in Tokyo? Like wow why don't we have that in Singapore??

Shibuya Center Street filled with all the good food and random stores

Curry rice for dinner!

Took this photo cuz the train said it's going to Ikebukuro and I couldn't wait to go Ikebukuro

End of day 2 back in hotel! Random milk bread (well that's what it says on the packaging idk) from the four stories Daiso in Harajuku (everything was 108￥ - inclusive of tax)
