Motosu Lake Diving around Mount Fuji

Motosu Lake is one of the Fuji Five Lakes. It is located at 900 meter, roughly 3000 ft, above sea level. This means you are altitude diving and it takes a bit more planning before, during and after the dive. Read up on things beforehand or get certified for altitude diving by a dive instructor.

If the dive site's name Haunted Mansion does not give you goose bumps already, consider the story that goes round about Lake Monster Mossy. Lake monster Mossy lives in the depths of Lake Motosu according to Japanese folklore. With a maximum depth of 122 meters, about 400 feet - there are many places Mossy can hide...

To make things even more scary - visit this place right before Halloween, like I did! OK, the fantastic Halloween night dive & BBQ party I missed - but when diving late afternoon on the night before Halloween the night falls early...

Halloween SCUBA Diving at Mount Fuji's Haunted Mansion

Lake Motosu's dive site Haunted Mansion is named after all the spooky death trees you can find underwater. When they appear when you get closer it looks like you are in a horror movie scene underwater.

As mysterious as those old trees already are - Dive center Motosuko Dive Resort goes one step further by adding carved pumpkins, skulls and scary masks. Are you scared yet? Make sure to check their Facebook page for the next Halloween dive & BBQ party.

Lake Motosu SCUBA Diving

You want to dive at Lake Motosu for the thrill of diving at Mount Fuji, doing an altitude mountain lake dive and seeing the volcanic seascape with often amazing visibility.

There are not a lot of different marine life species to discover at Lake Motosu but there are many small fishes around. Gobies are everywhere, try to spot the Amur Goby (Rhinogobius kurodai) and the Numachichibu (Tridentiger brevispinis). Also it is a bit of the local sport to search for green moss balls called Marimo (Aegagropila linnaei)!




Epsealon Towel Poncho

Change clothes easily after diving. A zipper on each side provides easy access to put your pants on / off.

Eisuke and me after diving at Lake Motosu.

About Motosuko Dive Resort in Motosu

Eisuke (Ace) Furuya is managing the dive shop and was my dive buddy at Lake Motosu. He will take good care of you.

The dive shop has everything you need, a lovely hot shower after a lake dive is the best. You can rent dry suits as well and I have to admit this rental was better than my own. There are some shops and restaurants nearby but they are likely to close at 5 PM latest, maybe summer time is different.

The water temperature was around 17 degrees Celsius / 63 degrees Fahrenheit (end of October). We were diving without a hood with a dry suit and gloves - it was not cold at all for me.

It was a great day of lake diving, thank you very much Eisuke!
