The most well-known form of Japanese bow is usually the long war bow which was the original prime weapon of Samurai warriors on horseback. These impressive bows were constructed from a layer of deciduous wood sandwiched between layers of bamboo, and could measure up to two and a half metres in length. The eighteenth-century Japanese bow shown here, however, is made from whalebone and is much smaller, measuring a mere 63cm when strung.
It is a kago hankyu, also known as a riman kyu after Riman Hayashi of Kii province who invented this miniature device. The bow fits into a lacquered carrying frame, and eleven arrows are slotted in alongside it. The arrows are constructed from dark red bamboo, and most of them have gilding between the fletchings. Six of them retain their small armour-piercing heads, whilst another has a small broadhead pierced with a heart shape. The base of the case is decorated with a triple overlapping diamond kamon (family crest) in gold.
The diminutive proportions of the kago hankyu could almost suggest that it was made for a child as a plaything. However, the bow and arrows were actually fully functional and potentially lethal. Indeed, their small size was a crucial part of their practical use. They had to be short because they were carried as defensive weapons by Japanese daimyo (nobles) and their senior staff when they were travelling inside palanquins (a covered sedan chair).
During the Edo period (1603–1868), the daimyo had to spend a lot of time in transit, complying with the demands of sankin kotai, the enforced biannual attendance at the court of the shogun. This resulted in a lot of long journeys in procession with large retinues of samurai and servants. If they were attacked on the road, a daimyo would be confined inside the palanquin, folded up into a kneeling position, and therefore had to be able to use his bow and arrows rapidly and effectively in very cramped conditions.
The daimyo also employed other weapons made on a smaller scale for the same reason, such as this kago yari (short spear) from the early Edo period, which is just over 80cm long.
