Usage
The opposite of 〜やすい: the action is difficult to carry out or the event rarely happens. It also inflects as an い-adjective. Use it for difficulty caused by the nature of the thing itself; for difficulty because of a lack of skill or ability, 〜ことができない or 難しい is more natural. 〜づらい is a close synonym but emphasises physical or psychological discomfort for the speaker.
