TOWING is a Japanese biotechnology startup that originated from Nagoya University. We
specialize in developing microorganism technology. Our focus lies in creating "high-function
biochar" by applying useful microorganisms to biochar, thereby obtaining various benefits.

Through our research in Japan, we have observed the following advantages facilitated by
our technology:
● Optimizing and neutralizing excessive increases in soil pH levels derived from the
introduction of biochar to the soil.
● Increase the capacity to produce nitrate nitrogen from organic nitrogen by at least
20% per day..
● Adding tolerance towards diseases related to bacteria and filamentous fungi in the
soil

By combining the above points 1) to 3), we have observed a yield increase of 1.1x to 1.7x for
certain crops such as tomatoes, soybeans, potatoes, etc.

Our core technology revolves around a specific cultivation process to achieve the optimal
mix of ammonifying bacteria and nitrifying bacteria. This method is akin to the fermentation
methodology employed in producing Japanese sake. Additionally, we have developed a
method that effectively enables bacteria to adhere to biochar.

We believe this technology will enhance the potential of biochar by providing additional
benefits for farmers when introducing it. Furthermore, we have succeeded in producing
high-function biochar using more than 100 types of biomass and have tested it with over 150
types of soil in Japan. These results will unlock the potential to upcycle local unused
resources. Together with the various merits achieved as stated above, this will create a
sustainable way of conducting agriculture.
