021 – Houkousei – Theorising the Temporal Aspect of Ikigai or Life Worth Living

What is important to your ikigai?

The lessons gained from our past and present experiences play a vital role in shaping the goals we set for our future. They serve as guiding lights, pointing us in the direction we wish to navigate our lives.

In this episode of the Ikigai Podcast , Nick discusses these ideas with Shintaro Kono and explores the role of the Japanese concept of hokousei in achieving ikigai.

Podcast highlights:

  • Mixed methods approach. At 2:26, Shintaro explains his study about theorizing the temporal aspects of ikigai among Japanese university students, and explains what it means to take a  ‘mixed methods approach’.
  • Houkousei. At 3:31, Shintaro defines houkousei.
  • Associations. Shintaro shares at 5:43 the two types of associations that he finds important in terms of houkousei and ikigai.

Dr. Shintaro Kono

Shintaro Kono is an expert in leisure behavior science and an assistant professor at the University of Alberta. Shintaro has been a regular guest on the ikigai podcast and has completed a three-part series on the subject of ikigai.

Mixed-methods approach

In 2019, Shintaro used a mixed-methods approach in a study he published on the temporal aspects of ikigai, or life worth living, among Japanese university students. Mixed methods is the research approach in social sciences combining qualitative and quantitative methods. Shintaro interviewed students after conducting a photo-elicitation task in which he asked students to choose pictures from their phones that they thought were related to their ikigai. The outcomes of the interviews allowed him to create his theory about ikigai in this population.


Houkousei means “directionality”, with hokou meaning “direction”. Like ikigai, it is a word commonly used in daily conversations by Japanese people. The students in Shintaro’s interviews use this term when they talk about where they are and where they want to be in the future, which shows that they perceive meaningful connections between their past, present, and future.


In his study, Shintaro found that when students formed explicit associations between the past, present, and future, they gained a strong feeling of ikigai. 

He identifies two important associations related to houkousei and ikigai:

  1. Cognitive association - all about the mind; mentally and psychologically, people connect their past experiences to their current life, and what they are valuing in the present moment to their future goals.
  2. Behavioral association - refers to the activities that people do which are either related to their past or future goals.

Life legacy and Life momentum

Shintaro mentioned in his research the relation of life legacy and life momentum with the cognitive and behavioral association.

Life Legacy

Life legacy is a linkage between the past and the present. It’s a feeling that you are building on top of something you have accomplished, acknowledging that certain experiences have a key role in shaping your past and current life. Shintaro says that life legacy can change over time; what’s really important is the magnitude of it, since the value of legacy may increase as people get older.

Life momentum is the opposite of life legacy; it’s the connection of people’s current state -- who they are, what they are doing, and what they value -- to their future goals. When you have this meaningful goal and things that you want to do, you have the feeling that you are almost floating and fired up; that’s the feeling of life momentum.

Life Momentum

Desire for a bright future

The concept of present-future linkage is somewhat similar to one of Meiko Kamiya’s seven needs, the desire for a bright future, because when people think about their goals, they do have this desire for a better future.

Shintaro thinks of it as a good connection to what he’s trying to propose, but he also pointed out the difference between his work and Kamiya’s: Kamiya’s work focused on people who experienced traumatic events, that they can have this sense of ikigai as long as they have this idea that their life can turn positive; however, his study focuses on students, who have not necessarily experienced those stressful events and therefore probably experience a different connection between their current and future lives.

Sense of control

In terms of taking control of our lives and life momentum, it’s important to understand that where we are right now and what our future holds doesn’t necessarily need to be linear. Our life direction might change along the way — we may experience ups and downs, and that’s okay. Shintaro believes that ikigai and houkousei are about the journey and process of getting there as much as actually reaching the destination.

State of mind

When it comes to life directionality, Shintaro believes that we should be in a mental space that facilitates creativity and brainstorming: able to review what we learned, what skills we acquired, and our personal growth, and relate these to specific experiences that we had, since this can help us identify important connections. Some experiences may be vague, which allows us to explore and have new perspectives.

The Ikigai Concept

This relates to ikigai, a beautiful but very complex concept: trying to define it in a sentence limits what you can understand, and instead people should let go of the definitions and be open to different interpretations or perspectives.


Yutori (mental space) is also needed in life momentum or life legacy. Shintaro thinks that it’s something that has to be looked into more. He says that there should be a mental space, something like reflection, a meditation session, maybe even a quiet walk outside -- whatever the yutori for each person is -- during which people can experience a moment when they are open to ideas, when they have freed their minds and have time to think and associate their past experiences with their current life and ponder the goals that they want to achieve.

Defining the past

Shintaro has found that a key condition for houkousei is defining the past -- looking for transformative, valued, comforting experiences that left vivid memories and influenced who they are today even if they no longer engage in those same sorts of experiences. There is a tendency to focus on more pleasant things, but actually negative experiences can prompt growth and have other lingering effects on one’s life -- which can be a great source of life legacy.


Negative Experiences

Clear goals

A second important condition for houkousei is clear goals, which Shintaro defined as ‘present-future links’. Clear goals are about what people want to accomplish in the future; the clearer the goals are, the more the people are drawn to them because it is easier to picture what they want to achieve. Everything else just flows from this and it’s easier for people to make cognitive and behavioral associations, which gives them life momentum.

Do not set goals that are shallow and superficial. It's important to have goals that are consistent with the authentic values that you really care about. - Shintaro Kono

Authentic Values

The interviews that Shintaro conducted with his students showed that students prefer to have a smaller number of clear goals than a large number of more nebulous ones. Short-term goals are clearer, specific, and tangible. For Shintaro, what’s important is for people to have goals that are consistent with the authentic values that they really care about, and not to set goals that are shallow and superficial.

Houkousei model

There are two perceptions of houkousei: life momentum and life legacy. Shintaro introduces the idea of ‘houkousei actions’, which allow people to connect the past, present, and future, and to identify directionality and movement (i.e., life momentum and life legacy). These actions are needed to bring about houkousei, and so people need to purposefully engage with the cognitive and behavioural associations needed to make connections and help them recognise which experiences they really value, and which goals they want to pursue.

Three-part series on the topic of ikigai

In episode four of the Ikigai Podcast, Nick and Shintaro talked about how valued experiences in leisure activities can be the most meaningful way for people to experience ikigai, and in episode 17, they discussed the importance of interpersonal experiences and ibasho. This is the third and final podcast in their exploration of ikigai.


Having directionality helps us achieve a meaningful life. This means having strong connections with our past, present, and future goals. In setting those goals, it is important to align our values with them. It's crucial to evaluate ourselves first, and to understand what really matters. We will inevitably learn more about ourselves in the process of achieving those goals, which will clarify which paths we should follow in the future.
