これから covers what starts now and what comes next

これから means “from now on,” “after this,” or “in the future.” Its starting point is the speaker's present situation. From that point, it can introduce an action that is about to happen, a new habit or rule that continues forward, or a future period that still lies ahead.

Three everyday patterns make that range easier to use. これから + action often announces what happens next: これから店内を案内します, “I will show you around the store now.” これからは + habit or policy marks a change from this point onward: これからは早めに出ます, “From now on, I will leave a little early.” これからの + noun describes the version of something that lies ahead, as in これからの仕事, “the work ahead.”

今から overlaps with これから when an action starts now. It puts 今, “now,” directly at the starting line, so it is especially useful when the exact timing matters: 今から十五分, “fifteen minutes starting now,” or 今から始めます, “we will start now.” Japan Foundation teaching material places これからCDを聞きます and 今からテストをします in parallel classroom announcements. Both naturally move into an immediate activity; 今から simply makes the present starting point explicit.

このあと means “after this” or “afterward.” In an activity with several steps, it naturally points from the current step to the next one. Japan Foundation Irodori material uses このあと、どうしますか when friends are deciding what to do next during an outing. これから can also ask about the next move, so this is a difference in framing, not a ban: このあと highlights what follows the current event, while これから looks forward from the present situation more generally.

A first shift at the café

Mina is starting a part-time job at a neighborhood café. When she arrives, the manager, Tanaka, explains the first step of her training.

The tour has not started yet, but it is the next action from the present moment. In a workplace, lesson, meeting, or appointment, これから + verb is a natural way to tell people what is about to happen. It gives the conversation a direction without promising that the action will continue forever.

Before the tour, Mina greets the manager and the other staff.

これからよろしくお願いします is a useful real-life phrase when a new relationship or shared activity is beginning. A word-for-word English translation sounds stiff because よろしくお願いします asks for goodwill and cooperation rather than naming one specific favor. Here これから sets the relationship's forward span: Mina and the staff will be working together beginning now.

After the tour, Tanaka checks the clock and gives the whole team a timed break.

The fifteen minutes are measured from the moment Tanaka speaks, so 今から is a particularly clear choice. これから would still point forward, but 今から makes the time calculation easy: start now, then count fifteen minutes. This is common when announcing a departure, beginning a task, or measuring how long something will take from the present.

The tour is complete, and Mina wants to know the next training step.

このあと treats the completed tour and break as the reference event, then asks what follows. That event-to-next-event sequence is why it sounds at home here. これから、レジの使い方を練習しますか would also be understandable and natural, but it would ask more generally whether register practice is what they are going to do now.

Tanaka answers yes, then gives Mina a rule for the working relationship ahead.

The particle は makes the period from now onward the topic. Tanaka is not asking Mina to raise one question immediately. He is establishing a continuing habit for future shifts. This is the natural shape for a promise, resolution, instruction, or change in policy: これからは気をつけます, “I will be careful from now on,” and これからは毎日確認します, “From now on, I will check every day.”

At the end of the shift, Mina has learned the layout, the register, and whom to ask for help. She tells another new coworker how she feels.

With の, これから modifies a noun. The phrase does not mean only the next task on today's list. It gathers the future work that begins from this point. Other natural phrases include これからの生活, “life from now on,” これからの予定, “the schedule ahead,” and これからの季節, “the coming season.”

The usual spelling is the kana これから. JMdict marks 此れから and 是から as rare kanji forms and labels the expression as usually written in kana. In ordinary messages, workplace talk, and conversation, kana is the useful default.

When choosing among the three expressions, ask what serves as the starting point. If you are simply facing forward from the present, choose これから. If “right now” is important to a clock, departure, or measured span, 今から is often clearer. If one activity is already in focus and you mean the step that follows it, このあと is often the natural frame. Those are practical tendencies, not rigid walls.
