EISSC, Encontro Internacional de Shakuhachi de Santa Catarina (Santa Catarina Internacional Shakuhachi Encounter) was founded in 2019 by Luigi Antonio Irlandini to create venues in Brazil for the music of the Japanese bamboo flute, the  shakuhachi. 

​

The First EISSC took place in the Santa Catarina cities of Florianópolis and Laguna in October 2019. The part in Laguna was organized by shakuhachi maker and player Henrique Elias Sulzbacher with support of the Coruja Buraqueira Bookshop and Dōjō Kobukan. The Florianópolis part was organized by Luigi Antonio Irlandini  with support of Fundação Cultural BADESC  and UDESC (Universidade do Estado de Santa Catarina). The First EISSC was modestly called "Encontro de Shakuhachi de Santa Catarina - ESSC 2019", but in reality it was already an international event because it brought Swiss shakuhachist Marco Lienhardt to teach and perform.

​

The Second EISSC took place in Florianópolis in September 2023 and was organized by Irlandini with support of Fundação Cultural BADESC, Research Group PROMUSI, UDESC, and the Research Institute FAPESC (Fundação de Amparo à Pesquisa e Inovação do Estado de Santa Catarina). The international guest was Rafael Hiroshi Fuchigami.

​The Third International Shakuhachi Encounter of Santa Catarina (EISSC-III) took place in  Florianópolis,  on September 23 - 26, 2026, carried out by the Department of Music of the Santa Catarina State University (Universidade do Estado de Santa Catarina - UDESC), coordinated by Prof. Dr. Luigi Antonio Irlandini, with a grant by FAPESC. The Third Encounter offered to the city's communities several activities centred on the shakuhachi and brought from Japan the renowned shakuhachi player Akihito Obama as well as, from São Paulo and Rio Grande do Sul, Brazilian shakuhachists Shen Kyomei Ribeiro, Danilo Tomic and Henrique Elias Sulzbacher, including the Ensemble Setsuen (with shakuhachist Bruno Adhmann and koto player Luiggia Maegava). EISCC-III focused on the creation of new repertoires for shakuhachi and guitar duo, promoting the Duo Obama-Oestreich, formed by Akihito Obama on the shakuhachi and Danton Oestreich on the guitar. In addition, EISSC-III has been expanded to include three other traditional winds instruments that form the basis of the ancient music ensemble Gagaku since the Heian Period (794-1185): these are the ryūteki (flute), the hichiriki (double reed instrument) and the shō (mouth organ). EISSC-III brought the Gagaku Trio, formed by Lish Lindsey, Thomas Piercy and Fabio Rambelli, respectively on each instrument. This has been one of the first few times in which these instruments and their musical repertoire - traditional and modern - have been heard and seen live in Brazil.​​​​​​​​​​​
