The CMB power spectra are measured using observations at 150 GHz with an instantaneous array sensitivity of $NET_array=23\, K \mathrms$ on a 670 square degree patch of sky centered at (RA, Dec)=($+0^h12^m0^s,-59^\circ18^\prime$). A continuously rotating half-wave plate is used to modulate polarization and to suppress low-frequency noise. We achieve $32\,\muK$-$arcmin$ effective polarization map noise with a knee in sensitivity of $= 90$, where the inflationary gravitational wave signal is expected to peak. The measured $B$-mode power spectrum is consistent with a $Łambda$CDM lensing and single dust component foreground model over a range of multipoles $50 \ell 600$. The data disfavor zero $C_\ell^BB$ at $2.2\sigma$ using this $\ell$ range of POLARBEAR data alone. We cross-correlate our data with Planck high frequency maps and find the low-$\ell$ $B$-mode power in the combined dataset to be consistent with thermal dust emission. We place an upper limit on the tensor-to-scalar ratio $r < 0.90$ at 95% confidence level after marginalizing over foregrounds.
