If there is one international trip you can do with only carry on, it's Japan. 

That was the pep talk I gave myself recently as I packed my suitcase, which looked Polly Pocket sized compared to the checked luggage I usually take overseas. 

Turns out my instincts were right.

Watch: If you're an anxious traveller, here are Paige's top tips for what to pack to bring the calm with you on your holiday. Post continues below.

Not only was one carry-on suitcase and a tote enough for two weeks in Japan, but next time I'll probably pack even less.

The secret to travelling light is identifying what you don't need (because it is already available at the hotel), what you do need to pack and what you can buy during your trip.

Let's start with what NOT to pack.

Japanese hotels aren't like regular hotels; they offer the most comprehensive range of amenities I've ever seen on my travels. 

In addition to all the things you'd usually find at a hotel, most Japanese hotels also provide pyjamas and skincare.

Even the most basic hotel I stayed in had two pairs of perfectly folded pyjamas in the bedside drawer and an assortment of sample-sized skincare, including cleansers and lotions. 

I packed my blow dry brush only to discover that most Aussie hair tools don't work in Japan, so that was a waste of precious suitcase space. I made use of the blow-dryer provided by the hotel instead. 

You don't even really need to pack a swimsuit, as swimwear of any kind is strictly prohibited at most Japanese hot springs. 

That's right, your Birthday Suit is all you'll need to enjoy one of the best traditional bathing experiences. 

This is what I DID pack for Japan.

I divided my belongings between a small carry-on suitcase and a soft tote bag. Together they fit within Qantas's 14kg carry on limit for international flights. 

In the suitcase I packed:

One very comfortable pair of trainers: Not a newish pair of flats that look cute with my outfits, a tried and tested pair of comfortable and supportive trainers because holidays in Japan generally require a lot of walking! 

Two jackets: I packed a leather jacket which I wore on the plane to smarten up causal outfits and a water-resistant trench coat with detachable hood for rainy days.

Four pairs of pants: I packed a pair of casual cotton pants, a pair of smart pants and two pairs of activewear pants.

I love these because they are stretchy and sweat-wicking with three pockets and a soft waistband.

A couple of basic tees: I only packed two tees for the first couple of days as I knew I was going to stock up on basics in Tokyo.

One wrap dress: An adjustable wrap dress is great for slightly dressier occasions. It's also easy to adjust the waistline at the end of the trip after too many visits to the 7/11. 

A small crossbody bag: The nylon ones fold into almost nothing and are great for on the go!

A cap: Not just for sun protection during the day but for bad hair days when I didn't have time to style my hair. 

In my tote bag I packed all my valuables and essentials for a long-haul flight which you can find here.

What you can buy in Japan.

Generally, I wouldn't plan to shop overseas. However, there are many items that are cheaper in Japan due to the exchange rate, lower retail pricing and tax-free benefits for tourists. 

This is what I stocked up on during my holiday:

Wardrobe basics: There is practically a Uniqlo on every corner in Tokyo, so I waited for this trip to purchase some new t-shirts, socks and sweaters at a cheaper price.  

Beauty and skincare: Stock up on your skincare while you are here because your money goes so much further. In Australia, I'm used to paying $11 for a single sheet mask. In Japan I was able to buy a pack of 7 high-quality sheet masks for the same price! 

Pre-loved designer fashion: If you are in the market for a designer handbag, you have to check out the vintage shopping in Osaka.

I was so proud of myself for travelling with carry-on only that I decided to treat myself to… another carry-on bag!

I scored a vintage Louis Vuitton Keepall 55 Travel Bag for only $770.

While that did unfortunately mean my carry-on suitcase needed to be checked in for the return flight, at least I proved to myself that I could travel light!
