The temperatures hit 30 degrees-plus as Niall O'Donovan's new-look Irish side crossed for seven tries and a second straight defeat of the gutsy Japanese.
Having scored a meagre four touchdowns in the first Test, two periods of early dominance in each half paid dividends for the Irish at the tightly-packed Prince Chichibu Memorial ground.
Munster team mates David Wallace and Frankie Sheahan bulldozed their way through for Ireland's openers inside the first eight minutes.
Two turnover tries for Japan's record try-scorer Daisuke Ohata either side of the interval kept the home side interested, but five Irish efforts in the third quarter, including two for Harlequins ace Gavin Duffy and Sheahan's second, sealed an eighth win of a ten-game season for the tourists.
Strong running from Munster wing Anthony Horgan sent Wallace over for Ireland's first score on three minutes. Fly-half and captain David Humphreys converted - to leapfrog Ronan O'Gara's Irish points scoring record of 525 by two - and added the extras to Sheahan's second try of the tour, set up by a clever inside pass from Peter Stringer, five minutes later.
Japan, with former New Zealand Maori flanker Hare Makiri and ex-Otago centre Reuben Parkinson to the fore, began to make inroads into the Irish defence and they deservedly closed up the deficit to 14-10 by the interval.
Returning number 10 Keiji Hirose banged over a 32nd-minute penalty before lighting wing Ohata sprinted 50 metres from an Irish turnover to score.
Nonetheless, with Japanese prop Shigeyasu Takagi sin-binned in first half injury-time for a ruck offence, three tries in the opening nine minutes of the second half from O'Donovan's charges put pay to any hopes the Cherry Blossoms had of an upset.
Humphreys notched the first two minutes in, after a neat break by Alan Quinlan, on as a replacement for the injured Eric Miller. Duffy added Ireland's fourth fifty seconds later from turnover ball and Tommy Bowe set up full-back Girvan Dempsey for another on 49 minutes.
Duffy added his second - his third try in four Tests - eight minutes later for a 40-13 buffer, with the score crafted well from an Irish lineout, dominated by Ulster youngster Matt McCullough lining out for his second straight cap, over halfway.
5ft 9in speedster Ohata then claimed his second of the afternoon - and incredibly his 46th try in 46 Tests - when making the most of a Parkinson pass out of a tackle.
Ireland though, missing 13 regulars, including eleven players currently on the Lions tour, the injured Malcolm O'Kelly and rested Anthony Foley, had the final say on 66 minutes. With players wilting in the heat, hooker Sheahan dived over for his second and Humphreys kicked the conversion to moved the points record up to 542.
Leinster's Kieran Lewis also came on in the closing stages to make his international debut.
