参上

Appears to be a Japanese coinage of Chinese-derived components, as a compound of 参 (san, “to come, to go”, humble connotations) +‎ 上 (jō, “up, upwards”, in reference to the relatively higher social standing of the other party to which one is going).

     実(じつ)はじきじきに参上(さんじょう)してお話(はな)し申(もう)しあげるとよいのですが、あの日以来(ひいらい)（どの日(ひ)なのか、それはあとでお話(はな)ししますが）頭痛(ずつう)がして起(お)きられませんので、手紙(てがみ)で失礼(しつれい)いたします。

     Although it would be better if I visited and talked to you directly, since that one day (which day, I shall tell you later) my headache will not stop and I cannot get out of bed, so please accept this letter.

This term has an inherent sense of visiting someone of higher social standing. It can be used to express humility about oneself, even when visiting someone of equal or lesser social standing.^[3]
