Although Takeo Yoshikawa is known as the "Encyclopedia of the U.S. Navy" in the Naval Command Department, he has never had experience in espionage work in the past. In the first few months of his arrival in Honolulu, his work did not go well.

Fortunately, the consul general in Hawaii, Kita Nagao (formerly the Japanese consul general in Guangzhou), is the former Japanese ambassador to Italy, Toshio Shiratori, who belongs to the "hawks" of the Ministry of Foreign Affairs. Inside the consulate, Kita Nagao gave Yoshikawa a lot of cover, and specially prepared a convenient and unobtrusive residence for him.

During the day, Yoshikawa was in charge of the detachment business at the consulate (due to the tension between the United States and Japan, many second-generation Japanese in Hawaii - these people who had dual American and Japanese citizenship because they were born in the United States applied to renounce their Japanese citizenship so that they could become authentic Americans), and at night and on his days off, he slipped out of a secret door in the back wall of the courtyard of his residence to search for information about the Pearl Harbor naval base.

Since the Naval Intelligence Department forbade him to intersect with other intelligence teams, Yoshikawa, who had just arrived and was unfamiliar with the place, thought of many ways to complete the mission.

For example, Yoshikawa once disguised himself as a Filipino laborer and infiltrated the construction team at Pearl Harbor. But he wore an olive-green collarless shirt and a hand-held lunch box to work hard at the base for a day, and he didn't even get into the dock area except for knocking on a few oil storage tanks during the break to make sure they were all filled with marine diesel.

Three months ago, Yoshikawa also pretended to be a native Japanese American who was offered a weekend job as an hourly worker in the Navy Club cafeteria. He had hoped to get some valuable news from the drunken American sailors, but he wasted six or seven weekends only learning to wash dishes and sweep the floor the American way. Because the old employees there didn't want a new Japanese kid to take away their chance to get a tip, Yoshikawa was pressed to the back kitchen next to the sink, and he could only go to the front hall to clean after the door was closed.

Yoshikawa even played with "big data", often wearing shabby clothes and pretending to be a homeless man to rummage through the garbage bins outside Pearl Harbor, trying to judge the number of ships anchored in the harbor from the amount of garbage, so as to calculate the departure pattern of Pacific Fleet ships.

Because of the U.S. Navy's environmental awareness (prohibiting the dumping of garbage in the port area), Yoshikawa's move is theoretically feasible, if he can accumulate enough historical data. But at this stage, this information is obviously not enough to help Yoshikawa complete the intelligence report to the Naval Intelligence Department every ten days.

In the end, it was under the advice of Consul General Kita that Yoshikawa found the right way to open the espionage work. Today, this Japanese-style izakaya on the slopes of the Aleva Mountains, the Shunshio Building, has become the main "work" place in Yoshikawa. Whenever he had time, Yoshikawa would come here and call a few geisha or nisai girls (Americanized second-generation Japanese women) to "spend time drinking". Sometimes he even stayed overnight in the store.

Of course, Yoshikawa's actions cannot be regarded as corruption and depravity. Because outside the window of the box on the second floor of the Chunchao Building, separated by a verdant sugar cane field, is the base of the US Pacific Fleet. Standing at the window, the east dock where battleships are docked, the west pier where aircraft carriers and heavy cruisers are docked, the factory strip near the shore, the Ford Island airfield in the center of the harbor, and the various ships that come and go on the main channel, everything that used to be seen only on the sand table model of the Ministry of Intelligence can be seen in full view.

Yoshikawa was able to find such a feng shui treasure thanks to a local Japanese businessman who wanted to denaturalize his children. Originally, in Yoshikawa's eyes, this kind of guy who was eager to get rid of his Japanese identity was simply the scum of the Yamato nation, and he didn't want to deal with these people at all unless he had to. However, Consul General Kita repeatedly advised him to make good use of the local Japanese ethnic group, and he pinched his nose and accepted several banquets. Unexpectedly, he unexpectedly found such an excellent observation point in the process of pushing the cup and changing the lamp.

Since then, Yoshikawa has lived an ideal life of eating and drinking for the country and picking up girls for business. Every day, eating Japanese food, drinking Japanese sake, listening to Japanese silk and bamboo music, flirting with a group of geisha, and observing the situation in Pearl Harbor through the geisha's sideburns and pink necks in his spare time, this job is really good.

"Morimura-kun, let's take a boat to see the reef in a while, okay?" A geisha named Kyoko asked delicately as she put a roll of sushi into Yoshikawa's mouth with her hand.

Boat trips to see coral reefs are a traditional part of Oahu's tours, and geisha get a lot of "kickbacks" for selling them. Two days ago, the U.S. Navy was blasting and leveling some coral reefs near the port so that water could be used by planes for take-off and landing. In order to get a closer look, Yoshikawa just took this geisha named Kyoko to sit there.

"If you want me to say, the weather is so nice today, let's go take a seaplane. I remember that Morimura-kun liked flying around the island the most. Naturally, another geisha in Yoshikawa's arms would not easily let go of the great opportunity to slaughter the "wronged boss", and hurriedly promoted another famous tourist project on Oahu.

If it was usual, Yoshikawa would have said yes. Flying around the island in a small plane can not only take in the airport and port; Moreover, it is very helpful to confirm the target of the attack from the air and understand the weather and air flow over the base. This month alone, Yoshikawa sat no less than seven or eight times.

A few dollars of money didn't matter to him anyway. The Navy Command Department gave him $100 a month for the investigation, and he had a salary of $150 a month. This amount of money is definitely a huge amount of money for ordinary people, plus all kinds of subsidies from the consulate, it is enough for him to squander it lavishly.

This is also the reason why Yoshikawa is so popular among the geisha and Nisai girls in the spring tide building. Who doesn't love tall, handsome and generous guests. As for some of his little quirks, such as not being interested in those beautiful scenery when sightseeing, but paying special attention to some boring things (Yoshikawa was observing the terrain at that time), and liking to chat with local old people (in order to obtain local meteorological information), etc., they were automatically ignored by them in front of the green dollar.

Yoshikawa also likes to take these girls with him when he goes out. First, the company of beautiful women can make work easier and more enjoyable. Second, this is also a cover for one's identity. Dressed in brightly colored local shirts and carrying a geisha with affection, Yoshikawa is easily mistaken for an ordinary tourist. Sometimes, even if you are a little closer to a sensitive area, you will not be questioned by the sentry.

But today, Yoshikawa has no intention of going out to play. Today, he also made an appointment with a guest - Hector, a second lieutenant officer in the US Army Air Corps. The second lieutenant was a logistics officer at Wheeler Airfield, located in the center of Oahu and a fighter base for the Army Air Corps, whom they had met just two days ago through a Japanese businessman who supplied meat supplies to the airfield.

At that time, the bold Yoshikawa invited Ensign Hector to a bar to play cards for the night, and generously forgave the other party's $6.5 gambling debt. In return, Hecht invited him to Wheeler Airport to watch the air show live.
