初級日本語 とびら I / TOBIRA 1: Beginning Japanese

A word of caution - this is a very new textbook still in its trial phase. Accompanying workbooks might not be published until 2022 or later.

Do note that there is another very popular, more advanced とびら textbook series from the same publisher which has been around for a long time.
