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...

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)!

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!
