YSOs are good laboratories to investigate the relationship between planet formation and disk evolution mechanisms. High-contrast (direct) imaging of exoplanets has the capability to detect such young planets around YSO, but the number of convincing planets around YSOs is minimal compared with other detection methods, and thus more reports of protoplanets are required to start the discussion of planet formation mechanisms. Here we propose Subaru/CHARIS broadband (JHK-band) mode for follow-up observations of J0337 that harbors a large cavity in its disk (Uyama et al. in prep). Keck/NIRC2 L^′-band observations detected potential companion candidates in the disk. Observing this system with CHARIS reference-star differential imaging and polarization differential imaging will provide the first detailed information of the disk surface at both total intensity and polarization intensity as well as investigating the companion candidates. If we confirm that they are real companions we will report the second system to PDS 70 that exhibits protoplanets in the cavity of its protoplanetary disk.
