The Tanzania Agricultural Research Institute (TARI Kibaha) and Japan International Cooperation Agency (JICA) have introduced new sweet potato varieties and cultivation methods from Japan to enhance the production of high-value crops. The new varieties, Tamayutaka and Koganesengan, are suitable for mid-latitude and warm semi-arid regions. The project, funded by JICA and supported by Terunuma Co., Limited and Matoborwa Co. Ltd., has verified the effectiveness of Japanese sweet potato varieties, cultivation techniques, and saccharification methodologies. This initiative is expected to increase farmers' income, build new food processing businesses, and create employment in Tanzania.
