The Miya Moto Shoko stores is one of the representative establishments of the Japanese empire. It is a marvelous exhibit continually of the possibilities in curios, silks, drapes, rugs, ivories woods and articles of virtu, carvings and a multitude of other things. The Miya Moto Shoko is purveyor to His Imperial Majesty's household by permit, and this means that everything that is wonderful may be seen there. Tourists who go to Tokyo and leave without seeing this store will have left without seeing one of the magnificent wonders of the modern world. The place should be included in every tourist's tablets in order to refresh his memory.
