Japanese billionaire and philanthropist Bungo Shimada has adjusted the price of his neo-Renaissance UES townhouse once again. Initially listed at an even $50 million, the mansion saw a reduction to $42 million before recently settling at $45 million. The 2015 reduction was a response to a depressed luxury market in the city during the period; perhaps the increase suggests a bit of a recovery.

At 14,000 square feet, and dating to the 1890’s, the home’s historical appeal is significant. A limestone façade speaks for itself.

Containing nine bedrooms—including staff quarters—within its six floors; the third floor is the master suite. There are two kitchens, one of which is currently reserved for catering, and a gym with dance studio. The top floor, at one time a handball court, now holds a bedroom, bathroom, kitchenette, and greenhouse.

The home also features a few hidden surprises: secret passageways. A coat closet floor opens to a basement stairwell, and a concealed door in the library opens to a card room. Such individual flourishes hold a bit of cachet to the right buyer.

In its more conventional spaces, the emphasis is on expanse and detail: high ceilings, usually featuring moldings, recessions, or coffering, limestone fireplaces, inlaid marble or oak floors, mahogany paneling, and a spectacular staircase with an ornate wrought-iron balustrade and hardwood handrail all beckon the city house-hunter with a significant budget, and a taste for the formal and historic.

Shimada is one of the owners of Japanese company Shimabun, a family business which recycles iron and steel.
