XVIII International Conference on Hadron Spectroscopy and Structure (HADRON2019)

A time-projection chamber, HypTPC has been developed at J-PARC for hadron spectroscopy experiments. HypTPC has a large acceptance thanks to the internal target system and a high-rate capability up to 1 MHz or even higher. So far, three experiments are planned with HypTPC, namely, H-dibaryon search experiment (E42), baryon spectroscopy experiment with (pi,pipi) reactions (E45), and a new exotic Lambda resonance search (E72). The status of these 3 proposed experiments and other possible future experiments will be introduced in this talk.
