In 2018, Hartono made his debut in the Chinese market by releasing a Mandarin-language version of his song "Electricity", which was released on February 7, 2018 in China, and February 9 elsewhere. Following that, later he released a Mandarin music video in February 12, 2018.

Coming from an English-speaking family, Nathan struggled with learning the Chinese language in primary and secondary school, describing it as an "unclimbable mountain" in a 2017 interview. It was not until he entered junior college when he discovered his newfound interest in learning Chinese. In the same interview, he added that learning the language "could open up a lot of opportunities." After his stint at Sing! China, he can finally complete sentences in Mandarin without pausing or inserting English words.

He returned to Singapore on Oct 9 to fans who received him at Changi Airport. Subsequently, in January 2017, he was appointed as an ambassador for the Committee to Promote Chinese Language Learning at an event graced by chairman and Parliamentary Secretary for Education Low Yen Ling, in recognition for his achievements and for his efforts to improve his Mandarin during the course of the programme, and will work with the committee to promote the learning of the Chinese language among Singapore students. He was also nominated for The Straits Times Singaporean of the Year award.

On 16 June 2016, Nathan acted in a web series drama called Can You Not?! produced by youtube channel TreePotatoes. It was a 10 episode web drama. Beth (Janice Chiang) is an ambitious, cutthroat producer. Jason (Benjamin Kheng) is a brilliant, but cocky director. Dave (Nathan Hartono) is a charming, handsome gentleman who happens to be their client. Put them together, toss in a high-stakes corporate film project and you get a recipe for mayhem!.

In 2016, Nathan's breakthrough showing at the first season of Sing! China made him more famous in Singapore as well as in other Mandarin-speaking countries. He had become the first Singaporean to pass the blind auditions (all three of Singapore's previous entries to the show's predecessor, The Voice of China, had failed to do so). Upon catching the attention of all four judges who participated in the show: Jay Chou, Wang Feng, Na Ying, and Harlem Yu, he selected Chou as his mentor.

He finished second overall in the final round that took place on October 7 at the Beijing National Stadium, after singing a mashup of classic hits "Moonlight Under The City" and "Women's Flower". This result was, nevertheless, the best a Singaporean (and any contestant who is not a Chinese citizen) has done in the competition since it went global in 2014.

On June 30, 2013, Nathan released an original single on his official YouTube channel titled, Thinkin Bout Love, which is only available digitally. In 2015, he released his second Indonesian single, Pasti Ada Jawabnya, three years after his first Indonesian album.

This was amid controversy over the media voting process at the end of the finals. While there was supposed to have been 81 judges, 92 votes were cast – 45 of which were for Hartono and the remaining 47 for eventual champion Jiang Dunhao. Notwithstanding, amid speculation among netizens that the contest was rigged, Hartono had expressed that he was not at all disappointed by the results.

He released his first EP, Nathan Hartono, which consists of 5 tracks, was a departure from his usual jazz work, exploring acoustic pop and folk style In December 2012, he released a Christmas single titled, I'll Be Home For Christmas and also recorded a track titled, "Layu Sebelum Berkembang" for the official soundtrack of Indonesian feature film Langit Ke 7.
