Rainy Day Things to Do in Lake Kawaguchiko & Fujiyoshida

Hi, it’s Daichi from KOKO Journey.
So… you came all the way to the Mt. Fuji area, and the weather forecast says rain.
And maybe your first thought is “If I can’t even see Mt. Fuji, what am I supposed to do?”
Of course, a clear Fuji view is amazing. But when the mountain disappears behind mist and clouds, the whole area feels quiet, moody, and very Japanese in a different way. Shrines feel more atmospheric, forests smell better, museums suddenly become a great idea, and Onsen hits even harder.
So if the weather turns during your trip, let me introduce things to do on a rainy day in Lake Kawaguchiko and Fujiyoshida.
Traditional Village: Saiko Iyashi-no-Sato Nenba
If you want something that feels old classic Japan, this is one of the best rainy day spots around Mt. Fuji.
Saiko Iyashi-no-Sato Nenba is a reconstructed village with beautiful thatched-roof houses, and many of them are now used as small workshops, galleries, and cultural spaces. Because everything is close together, it’s easy to walk around even in rain.




Address: 2710 Nenba, Saiko, Fujikawaguchiko-machi, Minamitsuru-gun, Yamanashi 401-0332, Japan

Wind Cave and Ice Cave


The Fugaku Wind Cave and Narusawa Ice Cave are natural lava caves formed by past eruptions of Mt. Fuji.
You can enjoy them even when it’s raining. Since they’re underground, they’re one of the easiest weather-proof activities in the area. Also, the surrounding Aokigahara Forest looks especially deep green and beautiful after rain, so even the drive there feels nice.

Kitaguchi Hongu Fuji Sengen Shrine


This is one of my favorite places around here.
Normally people think, “It’s raining, so let’s skip shrines,” but Kitaguchi Hongu Fuji Sengen Shrine actually feels better in misty weather. The giant cedar trees, wet paths, moss, and quiet atmosphere make it feel much more powerful.
It is dedicated to Konohanasakuya-hime, the goddess associated with Mt. Fuji, which gives the shrine an even deeper spiritual connection to the mountain.

Museum-Hop Around Kawaguchiko
Lake Kawaguchiko has many museums, which makes it great when the weather is not that good.
Here are some of them depending on what you’re into!
-Itchiku Kubota Art Museum
One of the most impressive museums in the area. Famous for its incredible kimono art, beautiful architecture, and peaceful atmosphere.

-Fujisan Museum
A great stop if you want to see Mt. Fuji through art, especially if the real mountain is hiding that day.

-Kawaguchiko Museum of Art
A quieter museum with photography, paintings, and rotating exhibitions connected to the Fuji area.

–Kawaguchiko Music Forest Museum
A very unique, slightly quirky museum with automatic musical instruments, antique music boxes, and European-style design.

-Kawaguchiko Konohana Museum
Cute, whimsical, and very different from the others. Great if you want something light and charming.

-Yamanashi Gem Museum
Small but fun, especially if you like crystals and jewelry.

Visit the Forest Aquarium in Oshino

The aquarium in Oshino focuses on freshwater fish from the Mt. Fuji spring water system, so it feels more local and nature-based than a typical big city aquarium.
One of the coolest parts is the doughnut-shaped tank, where you can stand in the middle and feel surrounded by clear water and fish.

Make Your Own Souvenir
If you’d rather do something instead of walking around in the rain, making your own souvenir is actually a fun option.
Kawaguchiko Craft Park
This is one of the easiest places to enjoy a hands-on indoor activity around Lake Kawaguchiko. There are several workshop-style experiences depending on the day, and it’s a nice choice if you want to do something a little creative while staying out of the weather.

Ishikorokan
I personally like Ishikorokan because it feels a bit more casual and local. You can make your own accessories by choosing the stones and parts you like, and they also have Mt. Fuji-themed charms, which makes it a fun place to create a more personal souvenir.




Dallas Village (Lake Yamanakako)

If you’re heading toward Lake Yamanakako, Dallas Village is another fun option. It’s especially popular for hands-on craft experiences like glasswork, and it works really well for couples, families, or anyone who wants to make a memory rather than just buy one.
Slow Down with Onsen (Day Spa)
A rainy day is the perfect excuse to slow down and enjoy one of Japan’s best habits: Onsen (Hot Springs).
Instead of chasing views in the rain, this is the kind of day where soaking in hot water, warming up, and doing a little less actually feels like the right plan.
Sensui (Fujiyoshida)
A convenient and casual day spa in Fujiyoshida, especially good if you want a relaxed local-style soak without needing a full ryokan experience.
Address: 4261 Kamiyoshida, Fujiyoshida, Yamanashi 403-0005, Japan
Fujiyama Onsen (Fujiyoshida)
One of the easiest and most popular rainy day options near Fuji-Q, with a spacious wooden bathhouse that feels more impressive than your average stop-in hot spring.

Address: 4 Chome-17-1 Shinnishihara, Fujiyoshida, Yamanashi 403-0017, Japan
Yurari Onsen (Narusawa)
If you want to spend a few slow hours indoors, Yurari is a great rainy day choice thanks to its variety of baths and comfortable day-use setup.
Address: 8532-5 Narusawa, Minamitsuru District, Yamanashi 401-0320, Japan
Benifuji no Yu (Yamanakako)
A great option near the caves, with multiple bath styles and good relaxation areas.
Address: 865-776 Yamanaka, Yamanakako, Minamitsuru District, Yamanashi 401-0501, Japan
Ishiwari no YU
A simpler, more local-feeling bathhouse on the quieter side of the Fuji Five Lakes area, good if you want something low-key rather than polished or resort-like.
Address: 1450 Hirano, Yamanakako, Minamitsuru District, Yamanashi 401-0502, Japan
Eat Local Food, Enjoy Sake and Beer
Rainy weather is perfect for slow food. If it’s cold or wet outside, this is your sign to sit down and enjoy some of the local specialties!
Try Houtou / Udon (Local Noodles)


Houtou is Yamanashi’s famous noodle dish — thick, flat noodles in a rich miso-based soup with vegetables. It’s warm, filling, and very comforting.

Try Basashi (Raw Horse Meat Sashimi)


If you’d like to try something a little more local and unexpected, basashi is one of the more unique dishes you’ll come across in the Mt. Fuji area.
It’s raw horse meat sashimi, usually sliced thin and served simply with soy sauce and other small condiments. It might sound adventurous at first, but it’s actually a well-known regional food in parts of Japan.
Of course, it’s not for everyone, but if you enjoy trying local specialties when you travel, this is definitely one of the more memorable ones.

Visit a Local Sake Brewery


If you’re interested in local drinks, checking out a Ide sake brewery or Fujiyama Beer can be a nice indoor stop. The Mt. Fuji area is known for its clean spring water, which makes it a good place to try regional alcohol.

Go for Indoor Fun at Fuji-Q Highland
If you still want something a little more energetic, Fuji-Q Highland can still work on a rainy day — depending on the weather.
Yes, some of the big outdoor rides may pause or close if conditions are rough. But there are still indoor attractions and entertainment options around the park area.


Final Thoughts
If Mt. Fuji is hiding today, don’t worry. A rainy day is simply an invitation to see a quieter, more authentic side of Japan.
Whether it’s the atmosphere of a shrine, a warm bowl of Houtou, or a slow soak in an Onsen, these are the moments that often stay with you the longest.

Safe travels!
