Japan Bicycle Promotion Institute.
The JBPI say that the Palace Cycling Course is a model course that is especially open to cyclists. Surrounded by castle moats and pine trees, this cycling course not only provides families with a quiet place for fitness and relaxation, but also contributes to preserving nature around the Imperial Palace.
