代表取締役 CEO

After graduating from university, I worked as a programmer for a Switzerland-based company in a Germany Branch. I developed business systems, web systems, and mobile applications for European car and luxury watchmakers. After returning to Japan, I became independent and established Grune Co., Ltd. I set up development centers in Asia such as Yogyakarta and Bali, Indonesia.

My hobbies are surfing, hiking, and snowboarding. I want to create an environment where I can enjoy IT development while traveling to mountains and beaches around the world. My mission is to let Grune members work and play to the fullest and enjoy their lives.

Internship Story


Erik Cervilla


Hi everyone, my name is Erik. I am Spanish but grew up in Switzerland. I studied International Management at a university in Germany. My courses required a mandatory internship in a company. Then, I remembered a friend of my family who runs a start-up in Japan. His name is Toshicika Yamashita, CEO and founder of Grune inc. After exchanging thoughts, he recognized my motivation and a compatible connection between the internship and my study. He offered me an internship at Grune Indonesia, a subsidiary company of Grune inc. Grune Indonesia provided me with salary, accommodation, and lent me a motorbike for my transportation. Grune Indonesia at that time had 2 offices, in Bali and Yogyakarta. I have never visited Indonesia and I was so excited.
