Okay, let’s tackle this. So Taku Akino has 16 years of experience in design, which is a good amount of time to establish himself in the field. His skills include design, web design, user interface design, logo design, brand design, illustrator, photoshop, html, and css. These are all in-demand skills, especially in Japan. Considering his experience and skills, I would estimate his hourly rate to be around $125. This is lower than what I would expect for someone with 20+ years of experience, but higher than entry-level designers. It's also worth noting that the location is Japan, which may have a lower cost of living and therefore a lower hourly rate compared to Western countries.
