What to Pack for a Mount Fuji Trip in October?

 Clothing
In early October, you can wear thin shirt for the upper and thin trousers for the bottom mostly; it’s even OK to wear summer clothes like dresses or short-sleeved shirts together with shorts on some sunny days. As the temperature gets cooler and cooler, you need to add a cardigan or trench coat to keep warm. For the lower body, change the thin trousers to thicker one like the sweatpants.

 Shoes
Casual shoes and boots are all appropriate options. 

 Others

Bringing a parasol is a good idea, as it provides both rain and sun protection. A hat and sunglasses can also be a good way to block UV rays and add a decorative touch. Additionally, you can pack sunscreen in your bag, just in case.

Travel Recommendations & Tips

 To make most of your day for visiting, you’d better start your day early. Or it is a wise idea for you to book a hotel room with nice view, so that you can see the splendid sunrise of Mount Fuji from the window if the weather is good when you get up.

 In sunny weather, you’re highly recommended to rent a bike and go cycling around the Lake areas, enjoying the fresh air and landscape of Mount Fuji from different angles; or take a walk in the Oishi Park where the grassland has mostly turned pink and red from green.

 Don’t go back too late, because the sun sets early and the perceived temperature will drop. It is best to bring a coat to avoid catching a cold.
