The Stardate for this episode sets its before the Stardate in "Virtuoso" and, while the few previous episode's stardates are unknown, "Tsunkatse" takes place quite a few episodes earlier. According to the atlas Star Trek: Star Charts by Geoffrey Mandel, the events of this episode are set before "Fair Haven" where the crew of Voyager must ride out a wave from the collision of two neutron stars. The production number for "Tsunkatse" is 232 and it does fall before the events of the previous three episodes. However, "Fair Haven" has a production number of 231, which should set the latter before the former. According to the atlas, this does not appear to be the case.
The writing around the ring is based on Japanese katakana
or "block script." Among many other uses, it is used to write out non-Chinese foreign words that the Japanese language lacks such as "news" and "computer." Japanese influences in a fighting ring have been seen before in the Star Trek Universe. In the season two episode "The Icarus Factor
” of Star Trek: The Next Generation
, Commander Riker and his father, Kyle, participate in an Anbojitsu ring that has Japanese kanji
(Chinese characters) decorating the ring.
