For many indie musicians in Japan, playing live is like a hobby that they do aside from a regular job. They often play at live clubs, called "live houses," jazz clubs, cafes and outdoor event spaces.
"Live houses" are basically music halls or rock clubs, which for the most part, have proficient sound & lighting staff and full backline equipment that is well maintained.
Jazz clubs commonly serve food & drinks in addition to live performances. Backline equipment is commonly provided at no charge, but all musicians are expected to pay for their own food and drinks.
