In Japanese, kocchi, socchi, acchi, docchi こっち, そっち, あっち, どっち mean "this way (toward me)," "that way (toward you)," "that way (away from us)," and "what way?" respectively. They're kosoado words related to direction, but they can also refer to sides, choices, and people.
The words kochira, sochira, achira, dochira こちら, そちら, あちら, どちら work the same way in some cases, but they're considered to be more polite.
