Photomultiplier tubes (PMTs) are extremely sensitive photon detectors, and their history is quite long. PMTs have a very wide application in the high energy and astroparticle physics field. In this document, some of recent activities about the PMT development are described. The Hyper-Kamiokande group has been developing two types of 50 cm diameter photosensors, both with much better photon detection capability than that of the Super-Kamiokande PMTs. The efforts for applying the innovative
