Mariko Moriwaki, 39, a Web editor at publisher Shogakukan Inc., draws a lot of attention from visitors to her office.

Among the gray suits of her colleagues, Moriwaki wears a kimono almost every day.

"Wearing a kimono is very cool in summer and warm in winter. I think it suits Japan's climate," she said in her office in Tokyo. "Many of my friends hope to wear kimono every day, but their working environment wouldn't permit it."
