Although the website is only in Japanese, but the data is presented in easy to understand numbers.  And as of this writing, the data shows the level for Nagano at 0.084μSv/hour which calculates to an annual level of0.081mSv/year.  The global average is 2.4mSv per year, so our level is well below the average.
