Discovering the joy of making something from nothing

When thinking about new materials or methods, there are some things which cannot be tried even at the lab.
I have run into this problem myself. How can I solve this issue?
Is there something I can do without using equipment? While asking myself these questions, I went through a process of trial-and-error.
And when I was able to figure something out using available equipment,
I remember feeling extremely happy.
Although it was a small device, because I made something from scratch,
I developed a fondness for the research that later used my discovery.
This had the effect of doubling my happiness.

This is it! The reason why I chose this company

Because this company is packed full of the things I want to do.

When I was at university I researched layered compounds.
Since lithium-ion batteries are also layered compounds, I became interested and started studying about them on my own.
Thanks to this, I became fascinated with rechargeable batteries and began looking for a company that worked with them when I started hunting for a job.
Among these, Santoku was much smaller than the others, yet still energetically engaged with rechargeable batteries.
Compared to other companies I visited, Santoku’s R&D was closely connected with actual production, and during my interview I felt that the things I developed here would be quickly applied to actual production.
Due to this enthusiasm for rechargeable batteries and the attraction of having such a short interval between development and production, I decided to turn down the other companies and go with Santoku, even though I was still in the middle of the job hunting process.
One more reason I chose Santoku is that they deal in rare earths, which are substances that pique the interest of my inquiring mind.
I believe that rare earths still hide many undiscovered possibilities.
Sometimes I imagine things like what if in the future batteries using rare earths could...?, and so on.
