In July of 2004, Rev. Murakami was assigned to Wailuku Hongwanji. During his tenure at Wailuku Hongwanji, he participated in the temple’s 105th anniversary in 2004 and 110th anniversary in 2009. He has been instrumental in increasing temple membership by recruiting more than 12 new members every year. As the principal of the Japanese Language School, he has implemented new programs that have increased student enrollment to over 90 students. New programs include culture days and educational trips to Japan. In 2012, the Honolulu Japanese Chamber of Commerce presented him with an award to recognize his efforts with the Japanese language schools throughout the State. In addition, he has been involved with planning and implementing temple improvement projects. Examples of such projects include the handicap accessible ramp between the main temple and the columbarium at the rear of the temple, the elevator from the ground level to the columbarium, and expansion of the columbarium and refurbishment of its altar for the temple’s 110th anniversary. He has also advised Eagle Scout candidates from Troop 40 to take on temple improvements projects. In 2011, he organized a committee to prepare a cookbook, A Taste of Dharma, to raise funds for the temple’s Vision 2030 program. The cookbook was an overwhelming success with the publication and sale of 1,500 copies in 2012.
