We've rounded up all the info you need to make your flight as enjoyable as possible. Follow our insider tips and you'll be cruising through airport security and exploring Yachi Onsen before you know it. What to pack in your hand luggage:

• A plane trip can be a stress-free experience if you bring the right stuff. Firstly, you'll want a few basic toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh set of clothes and a few magazines. Secondly, find a spot in your hand luggage for your laptop, a charger, any daily medications and perhaps a neck pillow too. Lastly, and most importantly, remember to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like box cutters, razor blades, fuel and fireworks. Sporting equipment like baseball bats, and items that could harm other people, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Don comfortable layers and opt for shoes that are flat, enclosed and easy to slip on and off.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.

A little pre-planning before your flight will help make your getaway to Yachi Onsen a piece of cake. Here are some handy hints for a speedy journey through security:

• Your travel documents and passport will need to be presented to airport security personnel. Have them easily accessible so you don't hold up the line.
• Your belt, coat, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn.
• For just a few minutes, you'll need to unplug from technology. Your phone, tablet and any other electronic gadgets also need to go through the scanner.
• Remove all gels and liquids from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
• It's also likely that you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
• Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, pack them in your checked baggage.
