More about the Brand Owner

HIROSHI OTSUKI

I live along the coast of Shonan and have grown up with the sea since I was a child, fishing, surfing, and boating. Originally, I was on the buyer side, but after making my own environmentally friendly niche products and wanting to tackle environmental issues even if it was a small thing, I found myself on the manufacturing side. Wanting to do something about footwear that is often washed away in the sea or river, it is a biodegradable flip-flops made in Japan that has been completed through repeated tests. We will continue to develop eco-friendly products so that we can contribute to the future of the ocean and the earth as much as possible.

~All from the desire to "protect the ocean"~

The amount of marine litter leaves me speechless. According to statistics from the Ministry of Economy, Trade and Industry, plastic (rubber) footwear products are the third most estimated product to use plastic. In addition, sandals are one of the things that are often washed away in leisure activities such as rivers and the sea. As you know, it takes a long time for plastic to decompose when it is washed into the ocean.

Perhaps due to differences in environmental awareness, surfers and other people who play in the sea have already expressed their opinions to companies that they want to change to more environmentally friendly materials because they are being swept into the ocean so much, and biodegradable products such as biodegradable footwear and wetsuits have already become commonplace.

Even Japan can't afford to lose! As a lover of the sea, let's make real biodegradable flip-flops that are not yet made in Japan, where everything goes back to the sea! and launched projects.

What are we doing?

Through trial and error...

First of all, a suitable one is selected from among the many biodegradability-promoting additives. Naturally, if you don't choose from 100% organic additives, you will deviate from the concept. It's still too early to mix it into solid plastic products, but the material of flip-flops is a foaming rubber sheet. If the amount of blending is not adjusted, "strain" will occur and it will not be molded well.

It is a fine powder to the limit, and since there are different colors in the product, colorless or white is a must. Also, flip-flops are a natural way to relax when you wear them, so you want to be particular about comfort. Don't be too soft, too hard, make the fabric too thin, not durable, or not heat resistant.

Commitment to the product

Don't turn off the lights of Japan's manufacturing!

Along with making biodegradable products, we were particular about the fact that everything was made in Japan.

Flip-flops originated in Japan, but are now rarely manufactured due to the wave of cheap overseas products. With the cooperation of one of the few factories, this SIX LINE brand is made one by one by the hands of master craftsmen.

Manufacturing in Japan makes it possible to take on various challenges

It's the ocean that I always let you play!

Nice voices from people who actually wear them. It is true that the price is high because they were too particular about raw materials and made in Japan. However, the people who choose the products and the people who wear them have feelings. When I listen to it, it's not flip-flops. I want to do something about environmental issues, even if it's just a small step, and I want to be a partner when I relax on the beach, in the pool, or in the city, and I want to leave a clean ocean, because I don't want the ocean that I always play in to get dirty! When he says that with a smile, I can't help but feel the deep feelings of the Japan about the real thing.
