In addition he was busy teaching religious education at the local government school. To the end of his stay there were some difficulties with a pastor from the Usambara mountains working in Dar es Salaam. After some time Yakobo asked to be transferred back to Tanga where he spent the rest of his active time as a pastor up to 1957, the year when he retired.
Mwishoni mwa kukaa kwake pia kulikuwa na matatizo pamoja na mchungaji kutoka Milima ya Usambara aliyefanya kazi pale Dar-es-Salaam. Baada ya muda Yakobo akaomba ahamishiwe kurudishwa Tanga mahali alipotumia muda wake akiwa kazini kama mchungaji hadi mwaka 1957, mwaka aliostaafu.
