Top Message

In 1990, the former owner founded a locksmith store in Hakata, Fukuoka Prefecture, the largest city in the Kyushu district, and has offered our technical services with high reliability and quality.
To offer electric lock installation work, we renewed our store as a' company limited' and started electrical construction work as well.
(Japanese say three as sometimes 'Mi' and sometimes 'Sun,' six as 'lo,' and nine as 'ku, ' so '369' could be said 'Sun Lock', it's like a play on words.)
We renamed our company as 'Sun Lock (369) Japan' because 369 is an indivisible number, which can be symbolized as ∞. Also, 369 can be pronounced in Japanese 'Miloku,' which means attractiveness. Therefore, we expect our company to grow indefinitely (i.e., ∞) and also expand from Kyushu to the entire country of Japan, and ultimately, worldwide, with attractiveness and strong and energetic passion.
We keep on developing our engineering skills and also offering our services with high reliability and quality.
