Chikubu (竹生島, Chikubushima) is a small island in the northern part of Lake Biwa in Shiga Prefecture, in the Kansai region of Japan.

[1] Located about 2 kilometers south of Cape Tsuzurao, Chikubushima is the second largest island in Lake Biwa after Okishima.

The entire island is a granite monolith with steep rock walls, with only one port located on the southern end.

During the Nara period, Gyōki is said to have built a chapel on the island to house statues of the Four Heavenly Kings, but its location and the veracity of this story is uncertain.

They originally stood in the Higashiyama ward of Kyoto, and are regarded as fine examples of architecture from the Azuchi-Momoyama period.
