Universal Studios Japan Hot in summer and very cold in winter
Universal Studios Japan is a large place, and both summer and winter will certainly drain your energy.
In summer, the waiting lines at Universal Studios Japan are kept somewhat cool with large blowers.
However, with so many people gathered in the queue, the heat can be very intense, so be sure to use fans, portable blowers, and disposable cooling materials to avoid heat stroke.
It is also important to keep yourself supplied with drinks as needed.
Vending machines are located throughout the park, so take advantage of them on hot summer days.
In summer, you will also feel heat waves due to the heat reflected from the ground. If you are concerned about sunburn, a parasol and sunscreen are also must-haves.
The crew will warn you not to use parasols while viewing the show, and you should remember to wear a hat as well.
In winter, try to use disposable body warmers or blankets.
Also, be aware that some attractions may get wet, so if there is a chance that your clothes may get wet at the attraction you want to ride, you should wear a kappa to avoid catching a cold, or remember to bring a change of clothes.
It is also important to bring an umbrella or kappa if the weather is forecast to be bad.
