Traditional Japanese style rooms are meant to smell of Igusa 

The smell of traditional Igusa (Rush grass) is something the Japanese people love, but some non-Japanese people do not like it.
If a Japanese-style room doesn’t smell of Igusa, it is likely that a different material which is not Igusa is used.
For example, Tatami mats with surfaces made from resins (TOKYO SERIES), or Japanese paper (ZEN SERIES).
