Throughout Otaru, there are plenty of unique boutiques selling arts and crafts, among other things. At Powerstone, they sell thousands of gem stones that are ideal to decorate the home, or for those who are interested in, or believe in the energy from these stones. This unique store can be found near the harbor along the main tourist area of Sakaimachi street. The idea behind these stones is that everything has a natural vibration, such as the earth, trees, water and stones, and these have power spots that give out a specific energy.

Throughout history these sacred stones have long believed to be amulets. The stones are said to purify and balance our mind, which can influence people and the environment. The stones come in a variety of choices such as birth stones, or constellation stones, or simply choose the color that you like. At the store there is a color guide of what each stone represents which can help make your choice, whether for yourself or as a gift. Whether or not you believe in power stones, they make for a great piece of jewelry or for an ornament to decorate the home.
