Toshiyasu Obata (72) is a wandering Japanese sweets artisan who once made confections favored by the imperial household. Never opening a business of his own, he wanders from shop to shop teaching other artisans how to make the finest Anko, a sweet bean paste. With just this skill alone, he's helped over 30 struggling sweets shops make a new start. The Anko he makes captures the aroma and flavor of the Azuki beans so well, even artisans from long-established shops are eager to learn his innovative techniques. We take a look at this rough-edged man, and see why he chose this lifestyle.
