Otsu is an antiquated Japanese word that would give fits to the best U.N. translator; depending on the context, it can mean strange, quaint, stylish, chic, spicy, witty, tasty, or romantic. Somehow, all these adjectives apply to the small Mission storefront that combines an art gallery, small-batch publishing house, and stationery store that embraces all things paper — books, calendars, journals, cards, posters, and notes, not to mention T-shirts and a variety of other cool stuff. Most are created with alternative materials like soy-based inks, recycled products, and tree-free papers. This is the perfect place to pick up a Milky Elephant postcard calendar by Eun-Ha Paek or a copy of Teen Power! by Joe Sayers in all its DIY glory.
