We present Subaru/SCExAO+CHARIS broadband ($JHK$-band) integral field spectroscopy of HD 34700 A. CHARIS data recover HD 34700 As disk ring and confirm multiple spirals discovered in Monnier et al. (2019). We set limits on substellar companions of $sim12 M_{rm Jup}$ at $0farcs3$ (in the ring gap) and $sim5 M_{rm Jup}$ at $0farcs75$ (outside the ring). The data reveal darkening effects on the ring and spiral, although we do not identify the origin of each feature such as shadows or physical features related to the outer spirals. Geometric albedoes converted from the surface brightness suggests a higher scale height and/or prominently abundant sub-micron dust at position angle between $sim45^circ$ and $90^circ$. Spiral fitting resulted in very large pitch angles ($sim30-50^circ$) and a stellar flyby of HD 34700 B or infall from a possible envelope is perhaps a reasonable scenario to explain the large pitch angles.
