That said, the natural scenery is very beautiful this month, so it is still worth visiting. In places like the Oishi Park and Yagizaki Park in the Lake Kawaguchi, there are large areas of blooming red and pink azaleas, purple lavender, and other kinds of colorful flowers. And staring from mid-June every year, the Lake Kawaguchi Herb Festival is held, and you’ll be obsessed with the picturesque view. 

Packing Guide for Mount Fuji Trip in June

 Clothing
During the daytime mostly, you can wear a thin shirt together with summer pants. Shorts, dresses, and skirts will do in fine weather. It’s recommended that you bring a thin coat or a shawl because the perceived temperature is lower in the early morning and after dusk.

If you want to visit mountainous areas, you’d better wear a thicker coat like the 3-in-1 jacket and thicker pants such as the wind-proof pants.

 Shoes
Considering the rainy season, it’s best to wear walking shoes or sneakers with water-proof and non-slip characteristics.

 Others

It’s crucial to pack the raincoat and umbrella in your suitcase. Additionally, sunhat, sunscreen with high SPF, and sunglasses are necessary to bring to protect against the strong UV rays.
