 note = {The exhibition facility of Torazuka Tumulus constructed in October 1980 was recently contaminated by microbial colonization on the walls and ceiling even though periodic fungicidal treatment had been performed. Although there is no clear scientific research
about the cause of the microbial contamination, it can be inferred that the increase of fungicide-resistant microbes may have been associated with the long-time use of fungicide.
 Because of this unfavorable situation, the committee for the conservation of historic sites in Hitachinaka city decided to change the fungicidal treatment for controlling microbes to exhaustive cleaning in November 2011 according to the concept of integrated
pest management. In the present study, we aimed to monitor the changes of microbial contamination, more specifically of air-borne fungal concentration, in indoor air at the exhibition facility of Torazuka Tumulus.
 The culturable air-borne fungal concentration in indoor air of the facility gradually increased until March 2013 after discontinuing fungicidal treatment. However, air-borne fungi decreased in October 2013 and were lowest in March 2014.Exhaustive cleaning was
performed two times (October 2013 and March 2014) and air-borne fungal concentration significantly decreased after the cleaning.
 From these results it is considered that periodic cleaning for removing the microbes and organic substances supporting microbial growth is one of the effective countermeasures for controlling microbial contamination in the exhibition facility of Torazuka
Tumulus although further monitoring of the microbial contamination is still necessary.},
