椿は春を告げる花で、古来より呪力をもつ神木されてきました。枝と葉で手を繋ぐ様は皆が仲良く助け合って生きる事の尊さを言わんとしています。

In ancient Japan, the tsubaki (camellia), a flower whose bloom proclaims the advent of spring, was believed to possess super- natural power.
The array of flowers linked by twigs or leaves symbolizes human society, nurtured by mutual assistance from human good will.
