The Song of Tentomushi (Japanese: てんとう虫の歌, Hepburn: Tentōmushi no Uta, lit.

There are seven young brothers and sisters who grow up peacefully supported by the love and care of their parents.

As a token of gratitude, the children present a trip to the couple on their wedding anniversary.

Though it is certainly a shocking tragedy to the youngsters, they cannot be left in sorrow for a long time; rather, they have to make efforts to jointly stand on their own feet without depending on anybody else.

So, their strenuous and daring living starts anew helping one another with brotherly affection, and their sincere attitude and lively activities gradually win admiration and encouragement from people of the community.
