Takuya Inaba(Bacchi)
Coordinator, Japan

Turning 'Wants' into 'Achievements' After graduating from university, I gained experience as a basketball coach before transitioning to human resources and organizational development in May 2023. I did this to deepen my coaching skills and to challenge myself outside of sports. By directly addressing organizational issues and fostering talent within companies, I encounter daily learning opportunities as I strive towards my dreams. To achieve this, I set goals and work towards transforming my 'wants' into 'achievements'.

I bring my passion for photography and film-making to work, creating people development and marketing films. I like many types of cheese, with my favourite probably being Wensleydale with some sort of dried fruit in it. Sometimes with crackers. And chutney. Maybe a glass of wine… What was I supposed to be writing about again?

Project Manager, UK

I look after clients from tender, right through to evaluation. Three of my four main clients are global, so it’s about managing time differences too. I am the 'go to' person for many other things as I've worked here since 1991. I'm open, honest and always have an opinion! Questions usually start with “you will know...” I like nothing more that being up a hill in the Lake District or French Alps and camping in Cornwall with family and friends.

Client Partner, Japan

"Exploring the transformation and growth of individuals"
Experiencing different industries such as rehabilitation, telecommunications and real estate sales, I came to the field of people and organizational development.
I strive to become who can 'unlock the potential of others‘ because I have been supported by various people providing me with 'opportunities' despite facing setbacks.
My favorite phrase is "Those with rich sensibilities are happier." Considering what makes people 'happy' as my guiding principle and I believe growth and contribution are extensions of this.
