Japanese cruiser Otowa : ウィキペディア英語版 | Japanese cruiser Otowa
was a protected cruiser of the Imperial Japanese Navy, designed and built by the Yokosuka Naval Arsenal in Japan. The name ''Otowa'' comes from a mountain in Kyoto, located behind Kiyomizu-dera. The waters from a waterfall at this temple were traditionally held to be a cure for all illnesses. ==Background== Authorized under the 2nd Naval Expansion Program of 1897, ''Otowa'' was originally intended to be the third vessel in the series. However, due to budget constraints, ''Otowa'' was redesigned with 10 percent smaller displacement, and with considerably lighter weaponry. The ship was completed in less than 20 months; its rapid construction time set a new record for Japan. She was laid down on 3 January 1903, launched on 2 November 1903 and completed on 6 September 1904.〔Chesneau, '' Conway's All the World's Fighting Ships, 1860–1905'', page 230〕 ''Otowa'' was the first ship to be equipped with the Japanese-designed Kampon water-tube boiler which developed compared to the pressure of the previous Niclausse boilers in the ''Niitaka'' class. The vertical triple expansion steam engines were identical to those of the ''Niitaka'' class with a slight increase in power.〔Chesneau, p. 230.〕 It was intended that the reduction in armor and armament in ''Otowa'' be partially offset by higher speed, but in fact ''Otowa'' was only very slightly faster than the ''Niitaka''-class cruisers. ''Otowa'' was also the last vessel to be constructed for the Imperial Japanese Navy with a naval ram.
