White Forest ~ full of color

Asahi Mountain Range to the North,
Iide Mountain Range to the South
A town surrounded by vast forests
This is Oguni, Yamagata

In the winter,
White blankets the mountains
White snow-covered countryside waits for Spring

In the summer,
White bark covers the beech trees
White forests stand calm in rain or shine


Shakunage flowers bloom pink, bright and soft
Rivers reflect the sun and shine like an emerald
Fallen leaves colored red and orange
The huge Ginko tree shining gold
These colors add spice to our lives

White Forest ~ full of color

Natural paints of this world use Oguni as their canvas
Creating beautiful views wherever we go
In the crisp clean air that always surrounds us
Would you like to see what this town could show?

The nature-rich town of Oguni is located in the northeastern part of Japan, surrounded by mountains.
About 94% of the town’s area is forest, 70% of which is deciduous, mainly consisting of beech trees.
In Oguni, the seasons shift very clearly. In the summer, there is lots of rainfall, and in the winter, a lot of snow.

The abundant snowfall leads to lots of water in Oguni’s land,
nurturing the life of flora and fauna and bringing with it many blessings.
For the white skin of its beech trees, the white bounty of its fallen snow,
and the white of the town’s campus mostly untouched by human hands,
we call our town “Shiroimori,” which means “White Forest.”

This is Oguni’s logo. The letters are shaped like a drop of pure, melted snow that carries abundant blessings.
In the symbol, water droplets gather together and crystallize into a snowflake. Three of these gather to become this symbol, which looks like the Japanese kanji for “forest.”
The logo implies that everyone in Oguni gathers to become one.
