Even on vacation The Penetrator can't catch a break. A young female scientist is kidnapped along with a few others to be forced to work on a nuclear weapons for sale on the black market. Mark Hardin just happens to be in Japan at the same time.
The end was pretty good. A little better than the lead. You always know what your getting with a Penetrator book. Sometimes more sex. Sometimes more violence. One thing you know. It's almost always point A to point B with a few detours in under 180 pages. Call me silly, but I'll be coming back for more.

The penetrator with so much blood on his hands needs a vacation to cleanse all the death. He ends up in Hong Kong and trouble soon follows. Leaving his trademark blue flint arrow at the death sites. A nuclear scientist is kidnapped in Japan and off the penetrator goes. He will pump bullets into Yakuza spraying blood like volcanoes as more and more gang members are hunting him down. The Yakuza boss is selling atomic artillery to the highest bidders. Heaps of inconsistencies with the Japanese cultural stuff but it's a men's bloody adventure and as always the Penetrator gets the bad guys.

The Penetrator is like a D level mens adventure series. It takes bits and pieces from all of the other series and cobbles them together. They are not bad but just kind of bland. This time he is on vacation in Japan and Hong Kong but is constantly attacked. He finds that a former gun runner he had used was mad at him from before and had gotten his Japanese contacts to kill him if he ever arrived in the country. Also a atomic scientist is missing who just happens to be a close friend of his benefactor's daughter. Of course the same group that is after him has the scientist. So he goes to take out the group and to save the scientist.

Not really recommended, like I said it is pretty bland. Not even so bad they are good like say Death Merchant, just dull. The character is okay but thats about it other than the writing is functional and least thry are quick reads.

After five prior adventures in the United States, “Tokyo Purple” sends Mark Hardin, vacationing in Hong Kong, to Japan, to go up against a crime ring that’s expanding into building and selling to the highest bidder tactical nuclear weapons.

This is an exciting, fast-paced adventure. It avoids the familiarity of the first book in the series by pitting Hardin against a different type of enemy. The setting, mostly in Japan, allows for some vivid local color, and for villains who don’t always use conventional weapons.

The battle between Hardin and Kamisori, the mastermind behind the tactical nuclear weapon scheme, is fought with a lance, samurai sword, battle axe, mace, and bow and arrow, among other traditional weapons. The fight is highlight of the book—and reminded me a bit of the epic fight scene between Michele Yeoh and Ziyi Zhang in “Crouching Tiger, Hidden Dragon.”

The Penetrator penetrates a Japanese crime gang who have kidnapped and force-humped a busty American atomic scientist. He poison darts a bunch of nameless nipponese dudes. He regular shoots a few too. The Penetrator did not cotton to Japanese breakfast. If I remember correctly, he only bones one chick this time. But she's a busty Asian.

What a wild ride!

They just don't write books like this anymore. While it was dated and has some sketchy ( dated) plot lines it is just a fun read.

Another men's adventure series from the 70's. Pretty much standard action, violence and sex. However a good standout is that the hero is healed and trained by an old Cheyenne Indian in the ancient mystic warrior ways of the Cheyenne. Recommended
