It was 10 am in the Tuesday morning. Clear day in February, Tokyo.
Morning sunlight was shining into the small park in the valley of the tall office towers near Ohsaki station on JR Yamanote Line.
In the glass walled sports club, senior men and wemen were swiming in the indoor pool for their morning exercise. Small kids in the nearby nursary school were taking a morning ride.
Trees seemed enjoying the quiet hours after the morning rash of the commuters working in these offices.
